Answer:
Circumference of a circle = 2πr
Diameter = 40 m So , Radius = half of Diameter , = D/2 = 20m
2 × 3.14 × 20
= 6.28 × 20
= 125.6
Area of Circle = πr²
= 3.14 × (20)²
= 3.14 × 400
=1256

Answer:
Step-by-step explanation:
Hello!!!
r = d/2 = 40/2 = 20 m
Circumference = 2(pi)r = 2 x 22/7 x 20 = 880/7 cm
Area = (pi)(r square) = 22/7 x 20 x 20 = 8800/7 cm square
Hope it helps!!!!
