Answer:
To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.
Step-by-step explanation:
P=i/rt

Answer:
4.4 cubic inches
Step-by-step explanation:
From the question;
- Radius of the cone is 1.2 inches
- Height of the cone is 2.9 inches
We are required to determine the volume of a cone;
Volume of a cone is given by the formula;
V=1/3πr²h
Therefore; taking π to be 3.142
Volume =1/3 × 3.142 × 1.2² × 2.9
= 4.373664
= 4.4 cubic inches (to the nearest tenth)
Thus, the volume of a cone is 4.4 cubic inches
It should be ten feet wide
2(17.5) + 2(10) = 55
