1 |
Problem |
A circular pizza has a circumference of 36 ft. What is the diameter of the pizza? |
|
2 |
Step |
The given circumference is |
36 ft |
3 |
Formula |
Find the circumference of circle |
C = 2πr |
4 |
Step |
Substitute the value in the formula |
36 = 2πr [π = 3.1415] |
5 |
Step |
After simplification |
36 = \$ 6.283 \times r\$ |
6 |
Step |
After simplification |
r = 5.73 ft |
7 |
Formula |
Here, the diameter is |
D = 2r |
8 |
Step |
Substitute the radius value in the diameter formula |
D = \$ 2 \times 5.73 \$ |
9 |
Step |
After simplification |
D = 11.46 ft |
10 |
Step |
The diameter of the pizza is D = 11.46 ft. |
|
