Answer:

$Circumference = 56.52 \cm\\\\Area = 254.34 \ cm^2$

Step-by-step explanation:

Taking π = 3.14

$Circumference = 2 \pi r= 2 \pi \times 9 = 18 \pi = 18 \times 3.14 = 56.52 \ cm\\\\Area = \pi r^2 = \pi 9^2 = 81 \pi = 81 \times 3.14 = 254.34 \ cm^2$

A gas pump fills 2^-2 gallon of gasoline per second. how many gallons does the pump fill in one minute?

astraxan [27]

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

Given that a gas pump fills 2^-2 gallon of gasoline per second.

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

$60\:\times 2^{-2}$

$=60\times \frac{1}{2^2}$ ∵ $a^{-b}=\frac{1}{a^b}$

$\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}$

$=\frac{1\times \:60}{2^2}$

$=\frac{60}{2^2}$

$=\frac{2^2\times \:3\times \:5}{2^2}$

$=3\times \:5$

$=15$ gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15

Alenkinab [10]

I would say that coordination doesn't belong. The other words seem to do with a person's personality or mentality, while coordination is more of a physical ability.
