Answer:
180 sq. in.
Step-by-step explanation:
The formula for the volume of a circular cone is V = (πr^2h)/3
So, 900 = (15πr^2)/3
2700 = 15πr^2
180 = πr^2 = area of the circular base
Answer: 162 in²
Step-by-step explanation:
The factors of 54 are listed below:
18 and 9 are the two factors that when plugged into the equation below, equals 54:

This can also be written as:

So now that we have our two factors, we need to multiply them by each other to get our answer.
18 times 9 = 162
Our answer is 162
Answer:
x=10, y = -20
Step-by-step explanation:
y = –5x + 30
x = 10
Substitute the second equation into the first
y = –5*10 + 30
y = -50 +30
y = -20
x=10, y = -20
