Surface area of the cylinder = 816.4 sq. ft.
Solution:
Height of the cylinder = 21 ft
Diameter of the cylinder = 10 ft
Radius of the cylinder = 10 ÷ 2 = 5 ft
Use the value of
= 3.14
Surface area of the cylinder = 
Substitute the given values in the surface area formula, we get
Surface area of the cylinder 

ft²
Hence the surface area of the cylinder is 816.4 sq. ft.
3/8+x=1
x=5/8
A 1 inch button is 5/8 inches longer than a 3/8 inch button.
Basically add up the given side lengths and subtract that from 180 for the triangles
Answer:
Step-by-step explanation:
Area = πr^2
r = diameter/2
r = 13/2
Area= 22/7 × (13/2)^2
= 22/7 × 169/4
Area = 132.79sqaure inch
