If the circumference is 110 find the area of circle
Answers
The circumference of the circle =110
2πr=110
r=110x1/πx1/2
r=55x7/22
r=5x7/2
r=30/2
r=15
Area of the circle
πr²
22/7x15x15
=707.142 cm²
circumference of the circle = 2πr
110 = 2πr
110×7/2×22 = r
divide by 11
10×7/2×2 = r
divide by 2
5×7/2 = r
r = 35/2
Area of circle = πr^2
= 22/7×35/2×35/2
divide by 7
= 22×5/2×35/2
divide by 2
= 11×5×35/2
divide by 2
= 55 × 17.5
= 962.5
