Answer:

(pi)4 or about 12.57 sq. units

Step-by-step explanation:

The base area of a cylinder is a circle.

Since we know that the radius is 2, we can use the equation A = (pi)r^2 to find the area.

So, using this formula, the area is (2)(2)(pi), about 12.57 sq. units (area is squared!)

If i read 60 pages in 1 5/12 hours how long will it take me to read 120 pages

zysi [14]

Answer:

Step-by-step explanation:

Direct proportion

60: 1 5 /12 = 120 : x

60: 17/12 = 120:x

Product of extremes = product of mean

60*x = (17/2)*120

$60*x=\frac{17}{12}*120\\\\60*x=17*10\\\\x=\frac{17*10}{60}\\\\x=\frac{17}{6}\\\\x=2\frac{5}{6}$

It will take 2 5/6 hours to read 120 pages

There are 62 girls in the 7th grade and 58 boys in the 8th grade. Each grade has 120 students. Which statement correctly compare

oee [108]

7th grade: 62/120 of the class is made up of girls; (120-62)/120 of boys.
8th grade: 58/120 of the class is made up of boys; (120-58)/120 of girls.

Looking at the info for boys only: Compare (120-62)/120 with 58/120. What do you see?

How many combinations of 7 candidates can fill 3 vacancies on a city council?

yKpoI14uk [10]

Answer:

35 combinations

Step-by-step explanation:

You have to use the formula for finding combinations in probability. It looks like this:

₇C₃ = $\frac{7!}{3!(7-3)!}$

so that gives you

₇C₃ = $\frac{7*6*5*4!}{3*2*1*4!}$

The 4 factorials cancel each other out, and when you do the math, you get 210/6. That divides evenly into 35. So there are 35 combinations.
