The Reuleaux triangle is shown in the attached figure

we know that

the area of a Reuleaux triangle is equal to

$A=\frac{1}{2} *(\pi -\sqrt{3} )*r^{2}$

where

r=18.6/2--------> r=9.3 m

$A=\frac{1}{2} *(\pi -\sqrt{3} )*9.3^{2}$

$A=60.96$

therefore

the answer is

61 m²

You meet with the financial aid office to discuss your costs for attending MGA next semester. Tuition is $113.67 per credit hour

Answer:

$1615.05

Step-by-step explanation:

First the cost. We know that tuition per credit hour is 113.67 and there is a flat fee of 660. This can be represented by 113.67h + 660, where h is equal to the number of credit hours.

Next, the amount paid. There are two constants of 350 and 400 already there. We can represent the remaining amount that needs to be paid by another variable, x.

Now, the cost needs to be equal to the amount you pay. We can replace h with 15 for 15 hours and solve for x.

113.67h + 660 = 350 + 400 + x

113.67(15) + 660 = 350 + 400 + x

1705.05 + 660 = 750 + x

2365.05 = 750 + x

1615.05 = x
