Question

Approximate, in miles, the circumference of a circle with radius equal to 7/11 miles. (Use 22/7 to approximate .)

Answer 1

Answer: 4 miles

Explanation:

The circumference of a circle can be calculated by using the formula:

= 2πr

where,

π = 22/7

r = radius = 7/11 miles

Therefore, circumference = 2πr

= 2 × 22/7 × 7/11

= 4 miles

Th circumference is 4 miles.
