Answer:
S=1444.4
Step-by-step explanation:
they already gave the formula so
13 is the height, 10 is the radius
plug it in to the formula (using 3.14 for pi)
S=2(3.14)(10)^2+2(3.14)(10)(13)
S=628+816.4
S=1444.4
Answer:
1444.4 ft.
Step-by-step explanation:
Using the formula, 2πr² + 2πrh, we can plug-in the unknown values.
'π' means pi; 'r' means radius; 'h' means height.
The radius is 10; the height is 13.
3.14 is used for pi.
(2π10²) + (2π10 · 13) = 1444.4.
Therefore, the surface area of this cylinder is 1444.4 ft.
