Problem

Calculate the volume of a cone, if r = 2 cm and h = 7 cm. (use \$π = (22)/7\$)

2

Step

Given that π (pi) is radius is and height is

\$(22)/7\$, 2 cm and 7 cm

3

Formula

Volume of a cone formula is \$V = (1/3) \times π \times (r)^2 \times h\$.

4

Step

Plug the values into the formula:

\$V = (1/3) \times (22)/7 \times 2 \times 7\$

\$V = (1/3) \times (22)/(\cancel7) \times 4 \times (\cancel7)\$

5

Step

Simplifying this expression:

\$V = 1/3 \times 22 \times 4\$

\$V = (88)/3\$

\$v = 29.33 cm^3\$

6

Solution

So, the volume of the cone with a radius of 2 cm and a height of 7 cm is \$29.33 cm^3\$.

Choice-A

This is the correct answer. It correctly follows the formula for the volume of a cone and provides an accurate calculation

Correct \$29.33 cm^3\$

9

Choice-B

Volume is measured in cubic units \$cm^3\$, not in square units \$cm^2\$ . This option is incorrect

Wrong \$62 cm^4\$

10

Choice-C

Volume is not measured in the fifth power \$cm^5\$. This option is incorrect

Wrong \$60 cm^5\$

11

Choice-D

Volume is not measured in the sixth power \$cm^6\$. This option is incorrect

Wrong \$65 cm^6\$
