Answer:

The answer is A.

Step-by-step explanation:

Given that the formula of area of triangle is, A = (1/2)×b×h. Then substitute the following values into the formula :

b = 10 units

h = 4 units

A = (1/2)×10×40

= (1/2)×40

= 20 units²

Find the surface area of a sphere with a volume of 36π in3.

swat32

First use known volume to solve for radius:
$V=\frac{4}{3}\pi r^{3}$
$r=\sqrt[3]{\frac{3V}{4\pi}}$
$r=\sqrt[3]{\frac{3(36\pi)}{4\pi}}$
$r=\sqrt[3]{27}$
$r=3$

Then use the radius to get the surface area:
$A_{surf}=4 \pi r^{2}$
$A_{surf}=4 \pi 3^{2}$
$A_{surf}=4 \pi 9$
$A_{surf}=36\pi\approx113.09$

If gasoline costs $1.99 per gallon and your car gets 27 miles per gallon what is your fuel cost if you travel 600 miles

mezya [45]

600 miles / 27 miles per gallon = 22.22 gallons

22.22 * 1.99 = $44.22 total cost
