Which of the following is r2 + 4s evaluated for r = 4 and s = 1.5?
11Alexandr11 [23.1K]
So if you have r^2 + 4s and r=4 and s = 1.5 r^2 is 4^2 which is 16 and 4s is 1.5 x 4 which is 6 so you do 16 + 6 which is 22 so the correct answer is a.

Please help don’t get it
Romashka-Z-Leto [24]

Answer:

A

Step-by-step explanation:

One complete turn is 1 perimeter (aka circumference).

We have to find the length it turned, hence, its circumference.

The formula for circumference (C) of a circle is:

C=2\pi r

Where r is the radius

The radius is HALF of diameter. Given diameter is 250, the radius is:

r = 250/2 = 125 feet

Now, substituting in formula we have:

C=2\pi r\\C=2\pi (125)\\C=250\pi\\C=785.4

So, it turned 785.4 feet with 1 rotation.

The correct answer is A
