Step-by-step explanation:
The surface area of a cylinder is 
where 
is the radius of the base of the cylinder and 
is the height of the cylinder.
So, the surface area of the cylinder is:
Answer:
263.9 cm^3 to nearest tenth.
Step-by-step explanation:
V = 1/3 π r^2 h
= 1/3 π 6^2 7
= 12 * 7 π
= 84π
= 263.8938
Answer:
Step-by-step explanation:
First you have to find the area of the full circle.
Area of circle:
A = pi radius^2.
A = 4 x 4
A = 16 pi squared
Area of rectangle:
3 x 3 = 9 cm
Now you have to subtract.
16 - 9 = 7 pi spuared
or if you answer wants to go a step farther:
21.98 squared
