Problem |
The circumference of a circle is 409 in. Find its diameter.(π = 3.14) |
|
2 |
Step |
The circumference of a circle is |
409 in |
3 |
Formula |
Circumference of a circle (c) |
C = πd |
4 |
Step |
Now plug the values into the formula |
409 = \$3.14 \times d\$ |
5 |
Step |
Divide 3.14 on both sides. |
\$409/3.14\$ = \$(3.14 d)/3.14\$ |
6 |
Step |
After simplification |
d = 130.25 in |
7 |
Step |
So, the diameter of a circle is 130.25 in. |
