Answer:
diameter = 4
Step-by-step explanation:
A=pi*r^2
12.566=pi*r^2
3.99988202979=r^2
r=1.99997050723
diameter = 2r
d=2(1.99997050723)
d=3.99994101446 =4

There are two hemispheres in there with radius 3 cm, so we can consider it as a whole one. and the other shape in between is Cylinder with radius 3 cm and height 4 cm.
Volume of whole ahape = volume of Cylinder + volume of sphere ~
<u>Volume</u> <u>of</u> <u>sphere</u> :




<u>Volume</u> <u>of</u> <u>Cylinder</u> :




<u>Volume</u> <u>of</u> <u>whole</u> <u>shape</u> :


If the circle has diameter 10,
A=πr²
A=25π
if there area of a square is 25π, then a side measures√(25π) = 5√π

Answer:
The answer is D
Step-by-step explanation:
When you divide 110 by 8 that equals 13.75 but when you divide 120 by 8 you get 15.
