area of shaded portion picture wise:
1. π(100-25)= 3.14*75= 235.5sq cm
2. (24*24)-(4*3.14*36) = 576-452.1 6= 123.84sq. cm
3. 22/7x49 - 98 = 154-98= 56sq.cm
4. π( 27^2-20^2) = 1034 sq.cm

ok
its not 48 its 49 square of 7
how?
oh
how does 49 come?
7 is radius of the circle because 14 is the diameter of the circle and diagonal of the square
so 49 is circumference of area?
i still didn't understand i know that 7 is the radius so how it becomes 49 instantly?
i wanna mark you brainliest but i marked her
thx for all you answer now i can do my holiday homework
