First you should know the value of the radius which based on the picture is 9 in, next step is multiply 9 two times itself, then after that multiply it with the equivalent of pi which is 3.14 once you get the answer multiply it once again with the height of the cylinder
The following information I've stated is derived from the formula

Pi (sorry I don't have the proper sign) multiplied to the radius then multiplied to the height of the cylinder

Once you've encounter a problem in which the radius isn't stated simple divide the diameter by two and you're good to go

Sorry if didn't explain it well

Answer:

Step-by-step explanation:

Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.

Michelle tried to solve an equation step by step. \begin{aligned} t-\dfrac35&=\dfrac45\\\\ t-\dfrac35+\dfrac35&=\dfrac45

valentinak56 [21]

Answer:

Step 2

Step-by-step explanation:

Michelle's step in trying to solve the equation is given below:

$\begin{aligned} t-\dfrac35&=\dfrac45\\\\ t-\dfrac35+\dfrac35&=\dfrac45+\dfrac35&\green{\text{Step } 1}\\\\ t&=1&\blue{\text{Step } 2} \end{aligned}$

Michelle made a mistake in Step 2.

The right hand side of Step 1: $\dfrac45+\dfrac35\neq 1$

Rather, the correct sum is:

$\dfrac45+\dfrac35=\dfrac75\\\\=1\dfrac25$

There are 1,200 students at Roosevelt middle school. There are 700 boys at the school. What percentage of the students at Roosev

Stella [2.4K]

Out of 1,200 students, 700 are boys. Therefore, the fraction would be $\frac{700}{1200}$ .

To convert this into a percentage, divide 700 by 1,200.

$\frac{700}{1200}$ = 0.583333 (or just 0.583 if you round)

Multiply 0.583 by 100 to get a percentage.

0.583 · 100 = 58.3

So, the percent of boys at the school is 58.3%.
