Question

find the area of semi circle diameter is 7 m

​

Answer 1

Answer:

19.25 sq.m

Step-by-step explanation:

d = 7m

so, r= 7/2 m

area of semi-circle = 1/2 × π × r²

                               = 1/2 × 22/7 × 7/2 × 7/2

                               = 77/4

                               = 19.25 sq. m.
