Answer:
SA = 156π
Step-by-step explanation:
The formula for surface area of a cylinder is
SA = 2πr² + 2πrh where r is the base radius, and h is the height.
We are given r = 6 and h = 7. Plug in those values and evaluate...
SA = 2π(6²) + 2π(6)(7)
SA = 2π(36) + 2π(42)
SA = 72π + 84π
SA = 156π
Answer:
11cm2
Step-by-step explanation:
11cm2x10cm2/2 = 55cm2
The answer is true i hope this helps
A has no solution so the answer is no solution.
Using the Pythagorean theorem:
6^2 = 5^2 + x^2
Simplify:
36 = 25 +x^2
Subtract 25 from both sides:
11 = x^2
Square root of both sides:
x = sqrt(11) (exact) or 3.316625 as a decimal
