Question

The perimeter of a semi-circular garden is 180 m. Find the area of the garden​

Answer 1

Answer:

Circle

Solve for area

A≈2578.31m²

C Circumference

180

m

Answer 2

Perimeter of the semi circular garden = 180 m

πr+2r=180m

=> r (3.14 + 2) = 180 m

=> r (5.14) = 180 m

=> r = 180 m ÷ 5.14

=> r = 35.01 m

Area of the semi circular garden = $\frac{\pi \: {r}^{2} }{2}$

= (3.14 × 35.01 × 35.01 sq. m) ÷ 2

= 1924.34 sq. m
