Question

a quadrant is cut off from the circle of circumference 44 cm then the area of remaining part of circle is options are 115.5
154 cm^2
51.5 cm^2
88 cm^2​

Answer 1

Answer:

a. 115.5 cm^2

Step-by-step explanation:

circumference= 44 cm

2π r = 44 cm

r = 44/ 2π

r = 7 cm

Now area of the circle = π r^2

22/7 *7*7 = 154 cm^2

area of quadrant = πr^2/4

= 154/4

= 38.5 cm^2

hence,area of remaining part = πr^2 - π r^2 /4

= 154 - 38.5

= 115.5 cm^2
