Answer:
The area of building c minus the area of building b equals the area of building a might be correct?
We know that
[volume of a sphere]=(4/3)*pi*r³
length of a circumference=42 ft
[length of a circumference]=2*pi*r-------> r=[length of a circumference]/(2*pi)
r=[42]/(2*pi)---------> r=6.6845 ft
[volume of a sphere]=(4/3)*pi*6.6845³-----------> 1251.11 ft³
the answer is 1251.11 ft³
The factors of 90 are: 2*3^2*5
or: 2,45, 3,30, 5,18, 6,15, 9,10, 1,90
in order: 1,2,3,5,6,9,10,15,18,30,45,90
Try socratic to answer that, it’s helped me
PR = QR
5n = 32 +n
subtract 1 n from each side
4n = 32
divide both sides by 4
n = 32/4 = 8
n=8
PR = 5n = 5*8 = 40
PR = 40
