1 |
Problem |
The diameter of a circular pond is 12 meters. What is the circumference of the pond? |
|
2 |
Hint |
Formula used |
\$"Circumference" = 2\pi r\$ or \$\pi d\$ |
3 |
Step |
The diameter of a circular pond |
12 meters |
4 |
Step |
Since we are given the diameter of the pond, we can use the second version of the formula: C = πd |
|
5 |
Step |
Circumference of the pond |
c = \$\pi \times 12\$ ⇒ \$3.14 \times 12\$ ⇒ \$37.68\$ |
6 |
Step |
Hence, the circumference of the circular pond |
\$37.68\$ meters |
