Answer:
Area = 1256 cm²; Circumference = 156.6 cm
Step-by-step explanation:
For a circle with radius r
Area = πr² ; Circumference = 2πr
For the given circle, r = 20 cm and π = 3.14 (given)
Area = πr²
= 3.14*(20 cm)²
= 3.14 * 400 cm²
= 1256 cm²
Circumference = 2πr
= 2 * 3.14 * 20 cm
= 125.6 cm
Step-by-step explanation:
Circumference of a circle = 2πr
= 2 * 3.14 * 20
= 40 * 3.14
= 125.6 cm
therefore the circumference of the circle = 125.6 cm
Area of the circle = πr²
= 3.14 * 20 * 20
= 1256 cm²
