Answer:
1470 in³, 716 in²
Step-by-step explanation:
The figure is a cylinder, and it's volume can be found using the following formula:
Volume of cylinder
= area of circle base ×height
= πr²h
Identify the value of r and h:
From the diagram, the radius (r) is 6 in. while the height (h) is 13 in.
Using the formula,
volume of cylinder
= π(6²)(13)
= 468π
= 1470 in³ (3 s.f.)
The surface area of a cylinder is the total area of all its faces, i.e. the sum of the area of its two circular bases and its curved surface area.
Formula
Surface area of cylinder
= 2πr² +2πrh
Surface area of cylinder
= 2(π)(6²) +2(π)(6)(13)
= 72π +156π
= 228π
= 716 in² (3 s.f.)
