Answer:
1. Area of ∆ = ½bh, b = 6, h = 3? (or 8?)( it's too blurry I'll just make two solutions to make sure :) )
If height is 3:
A∆ = ½(6)(3)
A∆ = 3(3)
A∆ = 9cm²
If height is 8:
A∆ = ½(6)(8)
A∆ = 3(8)
A∆ = 24cm²
Area of semicircle = ½πr², r = 6
As = ½π(6)²
As = ½(36)π
As = 18π
As = 56.54866776
As = 56.5cm²
At = A∆ + As
If height of ∆ is 3:
At = 56.5 + 9
At = 65.5cm²
If height of ∆ is 8:
At = 56.5 + 24
At = 80.5cm²
Hope this helps. ^^
