Question

Find the area. Around your answer to decimal places​

Answer 1

• Answer:

86.20 ft²

• Step-by-step explanation:

Hi there !

A = A₁ + A₂

A₁ =semicircle

A₁ = πr²/2

r = d/2 = 6.4ft/2 = 3.2 ft

A₁ = 3.14×(3.2ft)²/2 ≈ 32.15 ft²

A₂ =  trapezium

A₂ = (b + B)×h/2

A₂ = (5.1ft + 6.4ft)×9.4ft/2 = 54.05 ft²

A = 32.15 ft² + 54.05 ft² = 86.20 ft²

Good luck !
