Answer:
5027.2ft^2
Step-by-step explanation:
Given data
Radius= 40ft
The expression for the area covered is given as
A= πr^2
Substitute
A= 3.142*40^2
A=3.142*1600
A=5027.2ft^2
Hence the area covered is 5027.2ft^2

Answer:
60
Step-by-step explanation:
The outside of the circle will measure 360 all of our known values are added up to equal 240 so subtract it from 360 to get 120
Now divide 120 by half to get 60 since the outside is double the size of the inside
Hope this helps
Answer:
60
Step-by-step explanation:
Angle R is an inscribed angle so it is 1/2 of TS. Since a circle is 360 degrees, we find TS by subtracting (90 + 150) from 360 which gives us TS = 120.
x = 1/2(120) = 60 degrees
How many triangles exist with the given angle measures?
60°, 60°, 60°
A. Exactly one unique triangle exists with the given angle measures.
B. No triangle exists with the given angle measures.
C. More than one unique triangle exists with the given angle measures.
Answer:
The sum of the angles in a triangle is 180°, so the angles do form a triangle. Since two of the three angles are congruent, the triangle is an isosceles triangle. An infinite number of isosceles triangles exist with different side lengths. Therefore, more than one triangle exists with the given angle measures.
what is x??? Please explain.
Answer:
78°
Step-by-step explanation:
when two lines intersect it creates 4 seperate angles, here it gives us 78°, and we know that the angle across from it is the same, so they equal.
The students who attend Memorial High School have a wide variety of extra-curricular activities to choose from in the after-school program. Students are 38% likely to join the dance team; 18% likely to participate in the school play; 42% likely to join the yearbook club; and 64% likely to join the marching band. Many students choose to participate in multiple activities. Students have equal probabilities of being freshmen, sophomores, juniors, or seniors.What is the probability of the intersection of being a junior and participating in marching band?

Please help with last 2 domain and range
Answer:
See below for answers and explanations
Step-by-step explanation:
Top left: Since y can't be greater than 0 but is equal to 0, then the range is (-∞,0] and the domain is (-∞,∞) since there are no domain restrictions
Top right: Since both x and y have no restrictions, then the domain is (-∞,∞) and the range is (-∞,∞)
Bottom left: Since y cannot be less than 2 but equal to it, and x holds no domain restrictions, then the domain is (-∞,∞) and the range is [2,∞)
Bottom right: Since both x and y have no restrictions, then the domain is (-∞,∞) and the range is (-∞,∞)

Find the Circumference of a circle with a Diameter of 9 inches Group of answer choices 9 pi inches 9 pi inches^2 9 pi inches^3 108 pi inches
Answer: [tex]9\pi\ in.[/tex]
Step-by-step explanation:
Given
The diameter of a circle is [tex]d=9\ in.[/tex]
So, the radius is [tex]r=\frac{d}{2}=4.5\ in.[/tex]
The circumference is given by [tex]2\pi r[/tex]
Insert the values
[tex]\Rightarrow 2\pi \cdot 4.5\\\Rightarrow 9\pi \ in.[/tex]
Thus, the circumference of the circle is [tex]9\pi\ in.[/tex]

Answer:
Area of ¼th part of circle =¼πr²=¼×3.14×12²
=113.04in²
Area of rectangle ABCD=l×b=8×17=136in²
Area of rectangle DEFG=l×b=5×3=15in²
Total area : 113.04+136+15=264.04 =264 square inches.
Answer:
area = 263.04 in²
Step-by-step explanation:
area = (8 x 17) + (5 x 3) = (0.25 x 3.14 x 12²) = 135 + 15 + 113.04 =263.04 in²

Karen is adding a border to a rectangular poster. The border will have a uniform width of X inches and run along all four sides, so Karen uses the functions land wto model the length and width, in inches, of her poster after she adds the border. l(x) = 2x+ 18 W(x) = 2x+ 24 Which function correctly represents the total area, in square inches, of Karen's poster, when a border x inches wide is included in the area?
A. A(X) = 4x + 432
B. A(X) = 4x2 + +42x + 432
C. A(x) = 4x2 + +84x + 432
D. A(x) = 4x + 432
Answer:
B. A(x) = 4x² + 42x + 432Step-by-step explanation:
The area is the product of the width and the length:
A(x) = (2x + 18)(2x + 24) = 4x² + 42x + 432Correct choice is B
