Answer:
3054.0ft³
Step-by-step explanation:
Given parameters:
Height of cylinder = 12ft
Base radius = 9ft
Unknown:
Volume of the cylinder = ?
Solution:
The volume of a cylinder is the product of its base area and height;
Volume of cylinder = base area x height
= πr²h
r is the radius
h is the height
Insert the parameters and solve;
v = 3.142 x 9² x 12 = 3054.0ft³
Answer:
Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.
Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.
