Question

Plz solve it fast and stepwise

Answer 1

1)
Circumference = 2*π*radius
88 = 2*22/7*radius
radius = 14 metres
Area = π*radius*radius = 22/7*14*14 = 44*14 = 616 m^2

2)
Area of circle = π* radius^2
154 = 22/7*radius^2
So,
radius = 7 cm

Diameter = 2*radius = 14 cm

Answer 2

Hey friend your answer is here

Circumference of the circle = 88m
2πr = 88
πr = 88 ÷ 2
22/7 × r = 44
r = 44×7/22
r = 14
Area of circle = πr^2
= 22/7 × 14 ×14
= 22 × 28
= 616
