Well the formula to solve for the volume of a right circular cylinder would be, V=πr2h. For the radius, the number inserted into the formula would be half of the diameter measurement. Therefore, the radius would be 3 m. As for the height measurement, the number would remain the same of 5m. Once all figures are applied to the formula: V=π(3^2)(5), the answer could then be rounded either to the tenths or hundredths depending on what your teacher asks for. The answer in the end would come down to approximately 141.37 meters cubed.
Answer:
62 units^2
Step-by-step explanation:
The surface area of the prism is the area of the net. It consists of a vertical rectangle 3 units wide and 14 units high, which has an area of ...
(3 units)(14 units) = 42 units^2
and two "wings" that are each 5 units wide and 2 units high, so have an area of ...
(2)(5 units)(2 units) = 20 units^2
Then the total surface area is ...
42 units^2 +20 units^2 = 62 units^2

From fraction to decimal: divide the numerator by the denominator
From decimal to percent: move the decimal two places to the right. For example: 0.062=6.2%
From percent to decimal: move the decimal point two steps to the left. For example: 56%=0.56
From decimal to fraction: Rewrite the decimal number number as a fraction (example: <span>2.625=<span>2.6251</span></span>) an then Multiply by 1 to eliminate 3 decimal places, we multiply numerator and denominator by 10 cubed = 1000<span><span><span>2.625/1</span>×<span>1000/1000</span>=<span>2625/1000 and don forget to reduce if possible;)

Answer:
f(-7) = 21
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² + 4x
f(-7) is x = -7
<u>Step 2: Solve</u>
- Substitute: f(-7) = (-7)² + 4(-7)
- Evaluate: f(-7) = 49 + 4(-7)
- Multiply: f(-7) = 49 - 28
- Subtract: f(-7) = 21
