Answer 1

Answer:

1256, 125.6 (this is wrong sorry i didn't know that it wasn't a full circle)

Step-by-step explanation:

A) The area that the sprinkler is spraying is in a circle with a radius of 20 ft. The formula to find the area of a circle is pi*r^2, so the area of this circle will be 400pi (substitute 20 for r). Pi in this problem is 3.14, so 400*3.14 is 1256 feet.

B) The perimeter of the spray is technically just the circumference of the circle. The circumference is 2r*pi, so we substitute 20 for r again and we get 40pi. Again, pi is 3.14 in this problem, so 40*3.14 is 125.6 feet.

Those who will visit the garden more than 3 times in the next month will be those who visit 4, 5, and 6 or more times.

Out of the 75 surveyed, the total number of those are:

= 9 + 12 + 3

= 24

That would give a percentage of:

= 24 / 75

= 32%

This means that the best estimate for those who will visit more than 3 times is 32%.

Out of the total number of 516, that is:

= 32% * 516

= 165 members

A rectangular prism has a base with a length of 45 meters and a width of 11 meters. The height of the prism measures twice its width. What is true about the rectangular prism?
The height of the prism measures( )meters, so its volume is ( )cubic meters.

Answers

Answer:

The height of the prism measures 22 meters

The volume of the prism measures 10,890 cubic meters.

Step-by-step explanation:

The height is twice the width of the prism.

The prism's width is 11 meters.

2 x 11 = 22

The volume of a rectangular prism is calculated as:

V = l x w x h

So, the volume is:

V = 45 x 11 x 22

The volume is 10,890 cubic meters.

Hope this helps!

Answer:

Height = 22 Volume = 10890

Step-by-step explanation:

The width is 11 so multiply by 2 to get 22.

Then just do 45 x 11 x 22 which is 10890.
