It is equal to 3.
0.4+2.6=3
4-8=-4 olaá!! .....ANSWER
Answer:
V = 21.195 in ^3
Step-by-step explanation:
The volume of a cylinder is
V = pi * r^2 h
We know the diameter not the radius
d = 2r
3 = 2r
Divide by 2
3/2 =r
We know pi = 3.14 and h =3
V = 3.14 * (3/2) ^2 *3
V = 3.14 * 9/4 *4
V = 21.195 in ^3
If the tangent of angle 'A' is 7/9 , then
angle 'A' is either 37.87° or 217.87°.
