Answer:
hello the figure related to your question is missing attached below is the missing figure
answer : 157.08 m^2
Step-by-step explanation:
Calculate the area of the shaded area
= Area of the large circle - Areas of the small circles
= (( ) * D^2) - 2( (
) * d^2 ) given that the small circles are congruent
= (( ) * 20^2 ) - 2 ( (
) * 10^2 )
= 314.16 - 157.08
= 157.08 m^2
