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.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
