The equation for the surface area of a cylinder is 2πr^2+2πrh.
we substitute our values of the radius and the height to find our answer.
so 2xπx5^2+2xπx5x10 = 471.238898m^2
B is the right answer o think
Answer:
-23
Step-by-step explanation:
1. When multiply a positive number by a negative number, the answer will always be negative.
2. When we multiply any number by 1, that number will stay the same.
