Question in the picture, please give the answer and how you got it

Answer 1

Area of the circle is 78.5 sq. units.

Step-by-step explanation:

Circumference of the circle = 31.4 units

2 π r = 31.4 units

2 × 3.14 ×r = 31. 4 units

r = 31.4 / (2×3.14)

= 5 units.

Area of the  circle = π r² = 3.14 × 5 × 5 = 78.5 sq. units.
