Question

Help please! thank you in advance!​

Answer 1

Hello from MrBillDoesMath!

Answer:

48.8

Discussion:

Are of figure = area of triangle + area of semi circle

                     = 1/2 b*h                 + 1/2 ( Pi * r^2) =

                      = 1/2 *(6*8)             + 1/2 (Pi * 4^2) =

                      = 1/2 ( 48)                + 1/2 (Pi * 16)  =

                      = 24 + 8 Pi

                      = 24 + 8 (3.1)         (approx Pi as 3.1)

                      = 48.8

Thank you,

MrB

Answer 2

$Answer: \\ Area \: of \: triangle: \frac{6 \times 8}{2} = 24\\ Area \: of \: semi-circle:(3.1 \times {(\frac{8}{2} )}^{2})\div 2 = 24.8\\ Area \: of \: the \: figure:24 + 24.8 = 48.8 \: {ft}^{2}$
