Question

The area of circular region is 2646cm².Find it's radius and diameter​

Answer 1

Answer:

41

Step-by-step explanation:

Area of circular region=2646cm²

Area of circle=1/2πr²

1/2πr²=2646

r²=2×2646/π

r=√2×2646/π

r=41(approx).

Hope it helps you!!

Answer 2

Answer:

radius will be 29.01 and diameter will be 58.02

Step-by-step explanation:

area of circle = πr^2

according to question

2646 = πr^2

2646 = 22/7 × r^2

r^2 = 2646×7/22

r^2 = 841.90

r = √841.90

r = 29.01

diameter will be 2 × 29.01

diameter will be 58.02
