Formula = (a + b)^2 = a^2 + 2ab + b^2
x^2 + 4x + 4 + 9 = 0
x^2 + 4x + 13 = 0
The standard form would be 705,083.
To find the approximate volume of the volcano, you will use the formula for finding the volume of a cone.
V = 1/3 x pi x r^2 x h
1/3 x 3.14 x 8^2 x 1.95
V = 130.624
The approximate volume of the volcano is 131 cubic kilometers.
