Question

calculate the circumference.
formula:
c = πd
use 3.14 for π.
c = ? cm
round to the nearest tenth.

Explanation:

Step1: Identify the diameter

The diameter \( d \) of the circle is given as 22 cm.

Step2: Apply the circumference formula

The formula for the circumference \( C \) of a circle is \( C = \pi d \). We use \( \pi = 3.14 \) and \( d = 22 \) cm. So, \( C = 3.14 \times 22 \).

Step3: Calculate the product

\( 3.14 \times 22 = 69.08 \)

Step4: Round to the nearest tenth

Rounding 69.08 to the nearest tenth gives 69.1.

Answer:

69.1
