Answer:
379.94 mi²
Step-by-step explanation:
The area of a circle can be figured out with this formula: πr² (3.14 is π here, as it says in the directions).
We know the diameter is 22 miles. Divide that by 2 to get a radius of 11 miles.
The equation now becomes
3.14(11²)
11 squared is 121.
3.14(121)
I recommend splitting the 121 into 100, 20, and 1.
(3.14 * 100) + (3.14 * 20) + (3.14 * 1)
Multiply 3.14 by 100, 20, and 1.
314 + 62.8 + 3.14
Add 314 and 62.8.
376.8 + 3.14
Add 376.8 and 3.14
379.94 mi² is the area of a circle with a 22-mile diameter.

Answer:
$59.9088 (or approx. $60)
Step-by-step explanation:
0.12 x $53.49
= $6.4188
$6.4188 + $53.49
= $59.9088
Answer:
$13.52/4 = $3.38 per each towel.
4:13.52
1:n
To find n, divide 13.52 by 4; since, 4 divided by 4 gives us one.
