Answer:

1570

Step-by-step explanation:

the formula for surface area of a cylinder is:

A= 2πrh + 2πr²

π aka pi = 3.14

r = 10

h = 15

so now plug in the numbers

A = 2(3.14)(10)(15) + 2(3.14)(10²)

A = 942 + 2(3.14)(100)

A = 942 + 628

A = 1570

Answer:

The answer is 4.

Step-by-step explanation:

Vertical Angles are congruent.

You plug in 4 for x and you multiply the two to get you 112.

112-2=110, making the two angles the same angle measure.

Hope this helps :)
