Answer:
Perimeter = 133.681 cm
or 52.63 inches.
Step-by-step explanation:
"So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius."
let's use, πr + 2r
Diameter: 52
Radius: 26 (RAdius is half of the diameter)
πr + 2r (plug in)
pi x 26 + 2(26)
pi x 26 + 52
= 133.681 cm
or
= 52.63
F(0)=-3(0-1)
f(0)=-3(-1)
f(0)=3
Volume of bottom figure = 9 * 4 * 8.5 = 306 cubic centimeters
Volume of top figure = .5 * 1.5 * 2 * 4 = 6 cubic centimeters
TOTAL volume = 312 cc
6/144=d/720
d=6*720/144
d=30 defective units
