Question

Find the area of a quadrant whose circumference is 22

Answer 1

Answer:

Step-by-step explanation:

2πr/4 = 22

πr/2 = 22

22/7 * r = 44

r = 14cm

area = πr²

       = 22/7 * 14 * 14

        = 44* 14

        = 616cm²

area of quadrant = 616/4

                             = 154cm²

Answer 2

C is equal to 2pie r

Step-by-step explanation:

so we get r as 3.5

now apply quadrant formula =1/4×22/7×(3.5×3.5)

which is equ to 77/8
