Question

The circumference of the circle is approximately 125.66 centimeters. The shaded

region is of the whole circle.
Enter the area of the shaded region, in square centimeters. Round your answer to the nearest hundredth.

Answer 1

Area of shaded region=1256.30cm²

Explanation:

Circumference=125.66cm. Area=?

Formula for the circumference of a circle=2πr

π =3.142 r=?

Therefore circumference= 2×3.142×r

i.e 125.66cm=6.284r

r=19.996cm

Therefore;

Area=πr²

area=3.142 × 19.996×19.996

Area=1256.29733cm² ≈ to nearest hundredth= 1256.30cm²
