Question

Given that the volume of a cone is 2355cm3 and the area of its base is 314cm2.its hight is

Answer 1

V = 1/3 × π × r^2 × h

2355 = 1/3 × (314) × h (area of base = π×r^2)

h = 2355 × 3 / 314 = 22.5

Answer 2

Volume of cone = (base area * height)/3

2355 = (314 * height)/3

Step 1: Take 3 to other side

3 * 2355 = 314 * height

Step 2: Multiply volume with 3 to know the base area into height value

7056 = 314 * height

Step 3: Take base area to the other side and divide.

7056 / 314 = height

Step 4: Sigh, and celebrate the answer

height = 22.5 cm
