A sphere has a volume of 36π in3. What is the radius of the sphere?
amm1812

Answer:

r = 3 inches

Step-by-step explanation:

The formula for the volume of a sphere is the following:

V = (4π/3)r^3

You know the volume so plug that in for V:

36π = (4π/3)r^3

27 = r^3 (multiply by 3/4π to get r^3 by itself)

r = 3 (you take the cube root of r and 27 to get the value of r)

Hope this helps :)

Timothy has a savings account that he started five years ago to begin saving for college. The
torisob [31]

Answer:

A. $1500.00

Step-by-step explanation:

Assuming this is a simple interest savings account.

<u>Simple interest formula</u>

I = Prt

where:

  • I = total interest
  • P = principal amount
  • r = interest rate (in decimal form)
  • t = time (in years)

Given:

  • I = $225
  • r = 3% = 0.03
  • t = 5 years

Substitute the given values into the formula and solve for P:

⇒ I = Prt

⇒ 225 = P(0.03 ×5)

⇒ 225 = P(0.15)

⇒ P = 225 ÷ 0.15

⇒ P = 1500

Therefore, Timothy started the account with $1500.00.

The angles measures x and 4x are complementary angles. Which is the value of x?
Hitman42 [59]

<u>Answer:</u>

The angles measures x and 4x are complementary angles. The value of x is 36 degrees

<u>Solution:</u>

Given, two angles are x and 4x

We have to find the value of above given x  

We are also given that, given two angles are complementary angles for each other

So, we know that, <em>sum of any two complementary angles will always be equal to 180 degrees </em> 

Then, in the problem given,

x+4 x=180 \rightarrow 5 x=180 \rightarrow x=\frac{180}{5} \rightarrow x=36

Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees
