Question

The radius of a circle is 4 meters. Use

3.14 for π to find the
(a) circumference of the circle.
(b) area of the circle.

Answer 1

The circumference of the circle is 25.12 meters and the area of the circle is 50.24 square meters.

Step-by-step explanation:

(a) To find the circumference of the circle, we can use the formula C = 2πr, where r is the radius of the circle. Plugging in the given radius, we have C = 2(3.14)(4) = 25.12 meters.

(b) To find the area of the circle, we can use the formula A = πr^2. Plugging in the given radius, we have A = (3.14)(4^2) = 50.24 square meters.
