Answer: $50

Step-by-step explanation: Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)

It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.

Can somebody help me ??

fiasKO [112]

Answer: C

Step-by-step explanation:

$Formula: V=\pi r^2h$

We do not have the radius, but we do have the diameter. A diameter is twice the radius, therefore we can divide the diameter by 2 in order to obtain the radius.

$\frac{d}{2}=\frac{12}{2} =6$

Plug this info into the formula.

$V=\pi r^2h\\V=\pi (6)^2(7)\\V=\pi 36*7\\V=252\pi in^3$

There were some blue and yellow chairs arranged for a concert. The blue chairs were arranged in 36 rows with 131 chairs in each

DaniilM [7]

blue chairs = 36*131 = 4716

yellow chairs = 34*135 = 4590

So, there are 4716+4590 = 9306 chairs at the concert.
