To find a 2-dimensional shape like a cylinder you say V=πr²h
to find a 3-dimensional shape like a sphere you will have V=4πr³÷3
yes! what do you need?
Step-by-step explanation:
120+4=124 cause if 20 +4=24 is just the same thing they just added a 1at the beginning
Answer: 11
Step-by-step explanation: plug in 4 for x
3(4) - 1 = 12 - 1 = 11
Answer:
8 in
Step-by-step explanation:
RA = 4 in, RB = 2 in
oil height in A = hA = 2 in
Find oil height in B = hB
volume of oil in A = VA = π*RA² * hA
equal amount means volume of oil in B VB = VA
But VB = π*RB² * hB
so π*RA² * hA = π*RB² * hB
then
hB = hA *(RA/RB)² = 2 * (4/2)² = 8 in
