Geometry

Answer 1

B

Explanation:

circumference = 2πr

3.4x 2 x 3 = 18.84

Answer 2

19 feets

Explanation:

Given that , the radius of the circle is 3 feet . We need to find the circumference.

• We know that the circumference of circle is 2πr . So ,

=> C = 2 π r

=> C = 2 × 22/7 × 3ft

=> C = 18.84 ≈ 19 ft

Hence the circumference of the circle is 19 feet.
