Answer from: Quest

Hello!

the answer is:

the correct option is the option b.

$surfacearea=126\pi units^{2}$

why?

to calculate the surface area of the right cylinder, we need to use the following formula:

$surfacearea=2\pi rh+\pi r^{2}$

from the picture we know that:

$h=2units\\r=7units$

so, substituting and calculting we have:

$surfacearea=2\pi rh+\pi r^{2}surfacearea=2*\pi *7*2+2*\pi *7^{2}=28\pi + 98\pi =126\pi units^{2}$

hence, we have that the correct option is the option b.

$surfacearea=126\pi units^{2}$

have a nice day!

Answer from: Quest

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
