dmitriy555 [2]

1. Move the negative sign to the left.

- $\frac{19}{8}$ $X$ *-50

2. Use this rule: $\frac{a}{b}$ $*$ $\frac{c}{d}$ = $\frac{ac}{bd}$

- $\frac{19x*-50}{8}$

3. Simplify - $\frac{-950x}{8}$

4. Move the negative sign to the left.

-(-950x/8)

Surface area of a cylinder radius=10 height=15

Virty [35]

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
