Answer:

≈119.3

Step-by-step explanation:

The area for circumference is as follows:

C = 2\pi r\\or\\C = d\pi

The above equations mean the same thing, because the diameter is just 2 times the radius.

Anyhow, we insert this value into the equation...

C = 2\pi(19)\\C = 38(3.14)\\C = 119.32\\

This rounds to:

≈119.3

The area of the region under the curve of the function f(x) = 5x + 7 on the interval [1, b] is 88 square units, where b > 1.
djverab [1.8K]
We are given the area of the region under the curve of the function f(x) = 5x + 7 with an interval [1, b] which is 88 square units where b > 1 

We need to find the integral of the function f(x) = 5x + 7 with the limits 1 and b 

5/2 x^2 + 7x (limits: 1, b)

substitute the limits:

5/2 (1^2) + 7 (1) - 5/2 b^2 + 7b = 0

solve for b

Then after solving for b, this would be your interval input with 1: [1, b].<span />
