Question

A cone has a height of 14 centimeters and a diameter of 8.4 centimeters. What is the volume of the cone in terms of pie?

Answer 1

Answer:

$V=82.2\pi \ cm^3$

Step-by-step explanation:

-Given the cone's diameter is 8.4 cm and the height is 14 cm.

-It's volume can be calculated as follows:

$V=\frac{1}{3}\pi r^2h, \ h=14, \ r=8.4/2=4.2\\\\V=\frac{1}{3}\pi \times 4.2\times 14\\\\82.2\pi \ cm^3$

$\therefore V=82.2\pi \ cm^3$

Hence, the cone's volume is $82.2\pi \ cm^3$
