So then we do
large-small
V=(1/3)hpir^2
given
small=r=3 and h=5
V=(1/3)5pi3^2
V=5pi3
V=15pi
large, r=5, h=12
V=(1/3)5pi12^2
V=5pi48
V=240pi
large-small=240pi-15pi=225pi in^3
aprox 706.8582 in^3
Answer:
C
Step-by-step explanation:
Since triangles TUS and QRS are similar, if TUS is isosceles then so is QRS. This means that all corresponding proportions are at a constant ratio. So if TS=US, QT=RU and therefore a=7. Hope this helps!
Answer:
the answer is d
Step-by-step explanation:
No cs the absolute value is how far it is from zero and -5 is 5 spots from zero so he's incorrect
2 1/7 + 3/7 (3x-5)= - 4
2 1/7 + (9/7)x - 15/7 = - 4
15/7 + (9/7)x - 15/7 = - 4
(9/7)x = - 4
x = - 4 * 7/9 = - 28/9 = - 3 1/9
Answer is - 28/9 or - 3 1/9.
