Answer:
5 units
Step-by-step explanation:
The <u>volume of the cylinder</u> is the area of the circle multiplied by it's height. Therefore, the volume of the cylinder is πr² × h, which when simplified, gives us πr²h. Let's substitute the volume and the radius in the formula to find the height.
⇒ πr²h = Volume of cylinder
⇒ (π)(3²)(h) = 45π
Now, simplify the equation to evaluate the area of the cylinder.
⇒ (π)(3²)(h)/(3²)(π) = 45π/(3²)(π)
⇒ (h) = 45π/(9)(π) = 45/(9) = 5 units
The perimeter would just be the equation that they provided to you multiplied by 3 because a triangle has 3 sides, and it is an equilateral triangle, so every side is the same. You do the distributive property to solve the equation and get your final answer.
Answer:
B. 1.2 x 10^-1
Step-by-step explanation:
3.6 x 10^7 = 36,000,000
3 x 10^8 = 300,000,000
36,000,000 ÷ 300,000,000 = 0.12
= 1.2 x 10^-1
