Question

find the radius of a circle whose area of quadrant is 9.625sq.cm​

Answer 1

ANSWER HERE

the radius is 3.5cm

Step-by-step explanation:

first, multiply the area of the quadrant by four to get the area of the whole circle .

what you will get is 38.5 cm²

write 22/7 ×r²=38.5cm² then multiply both sides by the reciprocal of 22/7 .

what you are going to get is r²=12.25cm²

to get r, find the square root or 12.25 ,which is 3.5.

your radius is 3.5
