The surface area equation of a cylinder is:
2 * pi * r^2 + 2 * pi * r * h
Plug the values in:
2 * pi * 10^2 + 2 * pi * 10 * 10 is about 1256.64 units squared.
Answer:
39
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + 36^2 = c^2
225+1296 = c^2
1521 = c^2
Take the square root of each side
39 = c
Answer:
25π - 24 cm²
Step-by-step explanation:
area of circle:
A = πr²
A = π(5²)
A = 25π
Area of triangle:
base = 6
height = 5 - 1 = 4
(1/2)(6 * 4) = 12
there are 2 triangles so unshaded area is 24 cm²
Area of shaded region = 25π - 24 cm²
