Question

What is the volume of a cone with the given dimensions?

Diameter = 14 cm.; Height = 2 cm.
Round the answer to the nearest hundredth. Use 3.14 for pi.

a.
554.15 cu. cm
c.
404.15 cu. cm
b.
102.57 cu. cm
d.
764.15 cu. cm

Answer 1

Hey there,

Your correct answer to this question above would be 102.57 cu. cm

The FORMULA FOR THE CONE IS : Pi * r^2 * height/3
Plug in the numbers : 3.14 *7^2 * 2/3 = 102.57

And that would be your answer.

Answer 2

b. 102.57 cu. cm is the answer Solution: V=πr^2h The diameter is 14. To find the radius you divide the radius by 2 which is equal to 7. [Radius is 2 times diameter] V= 3.14×7×7×2 V= 102.57
