The volume of any solid whose base is uniform is V = Ah. Since the base is a sector of a circle, it’s area is defined by the equation A =  θ (r^2)/2, where  θ is in radians.

 90 degrees in radians is Pi/2. So the A = (PI) (r^2)/4

Therefore, V = [(PI) (r^2)/4]*h

What is the slope of the line on the graph?<br> Enter your answer in the box.
Firlakuza [10]

Answer:

I think this is the answer you are looking for. (See below)

Step-by-step explanation:

From the given graph it is noticed that the line is passing through many points.

The coordinates of three given points are (1,5), (-1,-1), (-1,-7)

If a line passing through two points (x1 ,y1) and (x2, y2) , the slope of the lie is defined by, m= y2 - y1/x2 - x1

The line passing through two points (-1,1) and (1,5). So the slope of the line is, m= 5 - 1 / 1 minus -1

m=4/2

Therefore, the slope of the line is 2.

Pls if this is wrong, let me know in the comments. I'm not really good at this topic in math but I hope it helps you. Sorry if it is wrong. Have a good day. :)

Elbert used to make $22 an hour, but got a 10% raise. How much more will he make in 40 hours work week with the raise
creativ13 [48]

Answer:

Elbert will Make $968 in 40 hours of work with the raise.

Step-by-step explanation:

Given:

Elbert makes $22 an hour.

He got 10% raise

Money raised on 10% = \frac{10}{100}\times 22=\$2.2

Now total money for per hour after raise  = \$22+\$2.2=\$24.2

Now to find the total money earned after 40 hours with raise we need to multiply total money for per hour after raise with number of hours.

Total money earned = \$24.2 \times 40 = \$968

Hence, Elbert will Make $968 in 40 hours of work with the raise.
