Answer:
1017.9
Step-by-step explanation:
Find the area of the circle on top first using 3.14*r^2
3.14*9^2 = 254.5
Multiply this number by the height, 4
254.34*4 = 1017.9
Step-by-step explanation:
let eqn be y - y1 = m(x - x1)
m = (9 - 1)/(-3 - (-7))
m = 2
sub (-7, 1):
y - 1 = 2(x + 7)
therefore, the equation is y - 1 = 2(x + 7)
