Question

Calculate the area and the circumference of the circle

Answer 1

Given , radius of circle is 0.8 yards

We have to find circumference and area of the circle

Formula for finding area of circle :- πr²

Area :- 3.14×0.8² sq. yards

Area :- 2.0096 sq. yards

Formula for finding circumference of circle :- 2πr

Circumference :- 2×3.14×0.8 yards

Circumference :- 1.884 yards

Answer 2

Circumference = 2 x radius x Pi

Circumference = 2 x 0.8 x pi

Circumference = 1.6pi or 5.024 yards

area = r^2 x pi

Area = 0.8^2 x pi

Area = 0.64pi or 2.0096 square yards
