the cost of fencing a circular field at the rate of Rs 12. per metre is Rs 2640 . find the radius of the field

​

Answers

Answer 1

Radius = 35 m 

Step-by-step explanation:Given:

Cost of fencing circular field is Rs 2640 at rate of Rs 12 per metre.

To Find:

What is the radius of the circular field ?

Solution:

 Let the radius of circular field be r metre.

Here , if we'll divide the total cost by per metre cost of fencing then we'll get circumference of the circular field.

★ Circumference = Total cost/Cost per metre ★

➯ Circumference = 2640/12

➯ 220 m

As we know that , formula of circumference is

★ Circumference = 2πr ★

⟹ 220 = 2 × 22/7 × r⟹ 220 = 44/7 × r⟹ 220 × 7/44 = r⟹ 20 × 7/4 = r⟹ 5 × 7 = r⟹ 35 = r

Hence, the radius of circular field is 35 metre.

Answer 2

Answer:

Solution given:

total cost =Rs 2640

rate=Rs 12/metre

We have

circumference of circle =[tex] \frac{total cost}{rate} = \frac{2640}{12} [/tex]

2πr=220m

r=[tex] \frac{220}{2π} [/tex]=35.01

r=35m(approximately)

the radius of the field is 35m.

What is the volume of a sphere with a diameter of 9.1m, rounded to the nearest tenth of a cubic meter?

Answers

Answer: V≈ 394.57m³

Step-by-step explanation:

The volume of the given sphere is approximately 391.3 m³.

What is the volume of a sphere?

The formula for the volume of a sphere is given by (4/3)πr³, where r is the radius of the sphere.

Given that the diameter of the sphere is 9.1 m, we can calculate the radius by dividing the diameter by 2:

Radius = Diameter / 2 = 9.1 m / 2 = 4.55 m

Now, we can substitute the radius value into the formula and calculate the volume:

Volume = (4/3) x π x (4.55 m)³

Volume = 4.18 x (4.55 m)³

Volume = 4.18 x (4.55³)

Volume = 4.18 x 93.859

Volume = 391.34482

Rounded to the nearest tenth of a cubic meter,

Volume = 391.3 m³

Therefore, the volume of the sphere is approximately 391.3 m³.

1 and 5 do not equal each other and there is no x left either so you can’t solve it.

In a class of 30 students, 12 have a cat and 19 have a dog. There are 6 students who
do not have a cat or a dog. What is the probability that a student chosen randomly
from the class has a dog?

Answers

Answer:

19/30

Step-by-step explanation:

30 students

12 have cat , 19 have dog , 6 no cat or dog

P dog = 19 have dogs/30 students total = .633333...

The likelihood that a randomly selected student in the class owns a dog is 19/30.

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Let A be the event that a student has a dog. Then, the number of students having a dog is 19, and the total number of students is 30.

The number of students having neither a cat nor a dog is 6. Therefore, the number of students having at least a cat or a dog is:

12 (number of students having a cat) + 19 (number of students having a dog) - 6 (number of students having neither a cat nor a dog) = 25

Thus, P(A) = number of students having a dog / total number of students = 19/30.

Therefore, the probability that a student chosen randomly from the class has a dog is 19/30.
