a. factor A = x^2 -30x + 225 = (x - 15)(x - 15)
side length =<u> (x - 15)</u>
b. add (x - 15) four times = 4(x - 15) =<u> 4x - 60</u>
Answer:
452.448cm^3
Step-by-step explanation:
Given data
Height= 25cm
Diamter= 12cm
Radius= 6cm
The expression for the volume of a cone is given as
V= 1/3*πr^2h
Substitute
V= 1/3*3.142*6^2*25
V= 1/3*3.142*36*12
V= 1/3*1357.344
V=452.448cm^3
Hence the volume is 452.448cm^3
Answer:
10.5 miles
Step-by-step explanation:
Ethan's favorite kind of exercise is running. He runs on a path that is 1.75 miles long. Last week, Ethan ran on the path 6 times.
