Find the area of the composite figurep

Mathematics
1 answer:
barxatty [35]3 years ago
8 0

Answer:

53.12 sq ft

Step-by-step explanation:

For triangle:

Base (b) = 8 ft

Height (h) = 7 ft

For semicircle:

Radius (r) = 8/2 = 4 ft

Area of the composite figure = Area of triangle + Area of semicircle.

=  \frac{1}{2} bh +  \frac{1}{2} \pi {r}^{2}  \\  \\  =  \frac{1}{2} (8)(7) +  \frac{1}{2} (3.14)(4)^{2}  \\  \\  = (4)(7) +   (3.14)(8) \\  \\  = 28 + 25.12 \\  \\  = 53.12 \:  {ft}^{2}

KiRa [710]
Charles can do the whole job in an hour, Bill can do 1/2 of the job in an hour, and Bob does 1/3 of the job in an hour.  Therefore, they do a total of 1+1/2+1/3=11/6 of the job in an hour, meaning it takes them 6/11 of an hour.  This is 6/11*60=360/11 minutes, or approximately 33 minutes.
