Radius of semicircle = 7 cm

Area of semicircle = $\frac{1}{2}$πr²

➙ $\frac{1}{2}$ × $\frac{22}{7}$ × (7)²

➙ $\frac{1}{2}$ × $\frac{22}{7}$ × 49

➙ $\frac{1}{\cancel{2}}$ × $\frac{\cancel{22}}{\cancel{7}}$ × ${\cancel{49}}$

➙ 1 × 11 × 7

➙ 77 cm²

∴ Area of Semicircle = 77 cm²

Answer 2

Answer:

area of figure = 77 cm²

Step-by-step explanation:

given -

radius = 7cm

to find -

Area of the figure

solution -

this figure is a semicircle.

And semicircle's area = 1/2 of circle's area =

1/2 × π × r² =

1/2 × 22/7 × 7 × 7 =

1×22×7×7 / 2×7 =

1078/14 =

77 cm²

Hence the area of semicircle = 77 cm².

hope it helps.
