Find the surface area. Use 3.14 for pi

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

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.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
