Question

Determine the volume of cone diameter 12cm and height 7 cm

Answer 1

Diameter = 12cm

So radius will be d/2

r = 12cm/2 =6cm

To find volume use the formula:

V=1/3*π*r²*h

=1/3*22/7*6*6*7

=1/3*22*36

=22*12

=264cm²

The volume is 264 cm²

Hope it helps.

Answer 2

Answer:

The volume of cone is $264 cm^{3}$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question   the volume of cone diameter 12cm and height 7 cm

We have find the value of volume of cone

Given diameter 12cm

Height =7cm

Then radius will be

$\frac{d}{2} \\\frac{12}{2} \\6cm$

We know that the volume of cone formula is $\frac{1}{3} \pi r^{2} h$

So, put the value of formula

We  know that the value of $\pi =\frac{22}{7}$

We get,

$\frac{1}{3} \times\frac{22}{7} \times (6)^{2} \times7$

$\frac{1}{3} \times22\times36$

Divide 36 by 3 we get,

$22\times12$

Multiply both numbers 22 and 12 we get,

$22\times12\\264 cm^{3}$

Hence the volume of cone is $264cm^{3}$
