Question

find the circumference of the rim of the basketball hoop by using 3.14 for π
a. 1,639.465 cm
b. 286.996 cm
c. 143.498 cm
d. 71.749 cm

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter.

Step2: Substitute given values

Substitute $d = 45.7$ cm and $\pi = 3.14$ into the formula:
$C = 3.14 \times 45.7$

Step3: Calculate the product

$3.14 \times 45.7 = 143.498$

Answer:

C. 143.498 cm
