Hello from MrBillDoesMath!
Answer:
r = = 57.6 (approximately)
Discussion:
Given: circumference of circle O = 362.14
The circumference of a circle of radius r, is given by the formula C = 2 *PI *2.
So we need to find the value of r in
2*Pi*r = 362.14
Divide both sides by 2*PI to get
r = (362.14)/ (2 * Pi) = (362.14)/ 6.283 (approximately)
= 57.6 (approximately)
Thank you,

Answer:
The answer is the option C

Step-by-step explanation:
Remember that
![a^{\frac{x}{y}} =\sqrt[y]{a^{x}}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bx%7D%7By%7D%7D%20%3D%5Csqrt%5By%5D%7Ba%5E%7Bx%7D%7D)
in this problem we have
therefore
![2^{\frac{4}{3}} =\sqrt[3]{2^{4}}=\sqrt[3]{16}](https://tex.z-dn.net/?f=2%5E%7B%5Cfrac%7B4%7D%7B3%7D%7D%20%3D%5Csqrt%5B3%5D%7B2%5E%7B4%7D%7D%3D%5Csqrt%5B3%5D%7B16%7D)
1 yard = 3 feet:
3.25 yards x 3 feet per yard = 9.75 feet.
1 foot = 12 inches:
9.75 feet x 12 inches per foot = 117 inches.
1 Cup = 8 Ounces
2 Cups = (8 Ounces) x 2
2 Cups = 16 Ounces
