Hey there! :)

Answer:

r ≈ 4.38 cm.

Step-by-step explanation:

Find the radius by working backwards using the equation A = πr²:

Given:

A = 60.24 cm²

π = 3.14

Plug these into the equation:

60.24 = 3.14r²

Divide both sides by 3.14:

19.185 = r²

Take the square root of both sides:

r ≈ 4.38 cm.

a student found the slope of a line that passes through the points (-3,10) and (5,-7) to be 3/8. what mistake did he make?
Yuki888 [10]
Slope = (y2 - y1) / (x2 - x1)
slope = (-7-10) / (5 - (-3)
slope is supposed to be -17/8
I am guessing she made her mistake by adding a negative sign...the student did : (-7 - (-10) / (5 - (-3) = (-7 + 10) / (5 + 3) = 3/8
