Answer:
D. 2 inches.
Step-by-step explanation:
<u>Given the following data;</u>
Volume of golf (sphere) = 4 in³
A golf ball is spherical in shape. Thus, to find its volume we would use the formula for the volume of a sphere.
![Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%20Volume%20%5C%3B%20of%20%5C%3B%20a%20%5C%3B%20sphere%20%3D%20%5Cfrac%20%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D%20)
Substituting into the equation, we have;
![4 = \frac {4}{3} * 3.142* r^{3}](https://tex.z-dn.net/?f=%204%20%3D%20%5Cfrac%20%7B4%7D%7B3%7D%20%2A%203.142%2A%20r%5E%7B3%7D%20)
Cross-multiplying, we have;
![r^{3} = \frac {12.568}{12}](https://tex.z-dn.net/?f=%20r%5E%7B3%7D%20%3D%20%5Cfrac%20%7B12.568%7D%7B12%7D%20)
![r^{3} = 1.0473](https://tex.z-dn.net/?f=%20r%5E%7B3%7D%20%3D%201.0473%20)
Taking the cube root of both sides, we have;
Radius, r = 1.016 inches.
To find the diameter;
Diameter = radius * 2
Diameter = 1.016 * 2
<em>Diameter = 2.03 ≈ 2 inches. </em>
D? I think it my solution is the close to this answer
Answer:
N = 85
Step-by-step explanation:
(236 + 542)+N = 863
778 + N = 863
N = 863 - 778
N = 85
Current Account Balance = $1,624.35
Initial Deposit = $975
Interest Rate (Simple) = 3.7% simple interest
Interest Earned = Current Account Balance - Initial Deposit
⇒ Interest Earned = $1,624.35 - $975
⇒ Interest Earned = $649.35
Now the Formula for Simple Interest is:
Simple Interest = ×
, where P is the initial deposit, R is the rate of interest and T is the time period
⇒ 649.35 = ![\frac{\text{975 x 3.7 x T}}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7B975%20x%203.7%20x%20T%7D%7D%7B100%7D)
⇒ T = ![\frac{\text{649.35 x 100}}{\text{975 x 3.7}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7B649.35%20x%20100%7D%7D%7B%5Ctext%7B975%20x%203.7%7D%7D)
⇒ T = 18
Hence, Jeremiah has had the account for 18 years.
Mary added 3/4 cups milk + 3 cups flour + 2/8 cups butter while baking. Her total batter = 3 cups.
3/4+3+2/8
3/4+12/4+1/4=16/4 = 3
