Question

Find radius and circumfarance whose area is 50.24

Answer 1

Step-by-step explanation:

area of circle = πrsquare

50.24 =22/7×r square

50.24×7=22 r square

r= 3.99812

circumference of circle = 2πr

=2×22/7×3.99812

= 25.131

Answer 2

Find radius and circumference whose area is 50.24

Step-by-step explanation:

circumference = 50.24, radius  r=50.242π, ∵ the circumference is always equal to 2πr.

So, r=50.242π=8.0cm

∴ the area is A=πr², we obtain A=π(8²)=201cm²
