Plz Someone Help Me Answer This Question With Solution

Answer 1

Step-by-step explanation:

semi perimeter=(2pie×r)/2

semi area=(pie×(r))/2

semi perimeter =154

semi area=3773

hope you understand

Answer 2

Answer:

Area = π r

D = 49

A = 22/7*49/2

= 11/1*7/1 or

= 11*7

=77cm²

Perimeter = 2πr

for semi circle = (2πr)/2

D=49

P=(2*22/7*49/2)/2

=(2*11*7)/2

=154/2

=77cm²
