Question

how to find radius of quater circle​

Answer 1

the radius is 5 itself

if you want to find the area, you need to use the formula for finding area of sector

that is

theta/360 × π r^2

here, theta = 90°

and r = 5

so, area of sector = 90/360×22/7×5×5

=1/4×22/7×5×5

= 550/7×4

=78.5714286/4

= 19.6428572
