Well the sum is 15+6=21. then you must do 81-21=60. So your answer must be t=60.
I think it is 10 because 18×10=180 but it is close hope this helps
V = 4/3 * pi * r^3
V= 4/3 3.14 * 3^3
V = 4/3 *3.14 * 27
27 * 3.14 = 84.78
V = 4/3 * 84.78 = <span>113.04
V = </span><span>113.04
hope this helps</span>
Answer:
I dont really know the answer.. but ill try; if its wrong I am so sorry;
Step-by-step explanation:
First you must get the area of a circle, which is; A= pi r squared
and all you have to do is fill it in like this;
A= 3.14 x 2.0
^
A= 6.28
