The radius of the base of a cylinder is 27 cm and its height is 37 cm. Find the surface area of the cylinder in terms of π

Nonamiya [84]

Surface area of a cylinder = 2 x Pi x r^2 + 2 x Pi x r x h

R = 27 cm
H = 37 cm

Take away the Pi seeing as you want to keep it in terms of Pi

2 x 27^2 + 2 x 27 x 37 = 3456 Pi cm^2
Your answer is B

Find the slope and y-intercept of -2x+5y=10

VARVARA [1.3K]

Simple...

you have:

-2x+5y=10

re-write in y=mx+b form...

-2x+5y=10
+2x +2x

5y=2x+10

Now divide....

5y=2x+10

$\frac{5y}{5} = \frac{2x+10}{5}$

y= $\frac{2}{5} x+2$

Now it's easy to see the slope and y-intercept...

Slope: $\frac{2}{5} x$

Y-intercept:2

Thus, your answer.
