Surface area of a cylinder radius=10 height=15

Virty [35]

Answer:

1570

Step-by-step explanation:

the formula for surface area of a cylinder is:

A= 2πrh + 2πr²

π aka pi = 3.14

r = 10

h = 15

so now plug in the numbers

A = 2(3.14)(10)(15) + 2(3.14)(10²)

A = 942 + 2(3.14)(100)

A = 942 + 628

A = 1570
