Write 7/10 as a sum of fractions two different ways

The required radius of the given cone is 3 inches which is the correct answer would be option (B).

What is the volume of a cone?

The volume of a cone is defined as the amount of space occupied by a cone in a three-dimensional plane.

The volume of the cone (V )= 1/3πhr²

The volume of a cone is 141.3 cubic inches. The height of the cone is 15 inches.

To determine the radius of the given cone.

The volume of the cone (v) = 1/3πr²h

Substitute the values of h and v, solve for r

⇒ 141.3 = 1/3π(r)²(15)

⇒ 141.3 = π(r)²(5)

Divided by 5π into both sides of the above equation,

⇒ 141.3/5π = (r)²

⇒ 9 = (r)²

⇒ (r)² = 3²

⇒ r = 3

Hence, the required radius of the given cone is 3 inches.

Answer:

A) B = 3V/h

Step-by-step explanation:

Given: The formula for the volume of a pyramid is V=1/3Bh.

From the above equation, we have to solve for B.

We use inverse operation to find B.

Multiply by reciprocal of 1/3 on both sides. the reciprocal of 1/3 is 3.

So, multiply by 3 on both sides, we get

3V = 3*1/3*B*h

3V = B*h

Now divide both sides by h, we get

3V/h = Bh/h

3V/h = B

Therefore, the answer is A) B = 3V/h

A) B=3V/h

Multiply both sides by 3 to get 3V=Bh. Divide both sides by h, and you get 3V/h=B
