Question

Answer this question with step​

Answer 1

Answer:

shaded region are semi circles

so,

area of semicircles is πr^2/2

πr^2/2 + πr^2/2

πr^2

π* 28^2

28*28*22/7

2464cm^2

Answer 2

Step-by-step explanation:

Side of square =28

area of square =s*s

= 28*28

=784cm2

we have two semicircle with diameter 28 cm

the radius if semicircle is d/2

=28/2 = 14cm

now area of two semicicle = 22/7*14*14

=616cm2

area if shaded region = area of square -area of 2semicircle

= 784 -616

=168cm2
