shana sells
t-shirts. it costs shana $6.50 to buy
each t-shirt. she also pays $150 each
month to rent equipment to add print to the t-shirts.
shana sells each
t-shirt for $12.
write an
inequality that can be used to determine the number of t-shirts (t) shana must
sell each month in order to make a profit for the month.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
