Answer:
then find the answer by yourself by putting the values and multiplying them
Given : radius of a circle be 25.2cm
To Find : Circumference of the circle
Circumference of the circle
area of semicircle,
Solution:
Circumference of a circle = 2 πr
r = radius = 25.2 cm
π = 22/7
Circumference of the circle = 2 (22/7)25.2 = 158.4 cm
Area of a circle, = πr²
r = radius = 25.2 cm
π = 22/7
Area of semicircle, = (22/7)(25.2)²
= 1995.84 cm²
Area of semicircle, = (1/2) πr²
r = radius = 25.2 cm
π = 22/7
Area of semicircle, = (1/2)(22/7)(25.2)²
= 997.92 cm²
