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: 2.7d + 24.3
Step-by-step explanation: Easy
The value of x, y and z from the system of equation are -1, -8 and 5 respectively.
Data;
- -2x + 6y + 3z = -31
- -3y + 7z = 59
- 2z = 10
<h3>System of Equation</h3>
To solve this problem, we have to solve the system of equation using substitution method.
From equation (iii)

let us substitute the value of z into equation (ii)

Let's substitute the value of x and y into equation (i)

From the calculation above, the value of x, y and z are -1, -8 and 5 respectively.
