Answer:
y = 1/4x^2 - 4.
Step-by-step explanation:
Vertex for is:
y = a(x - 0)^2 - 4 where a is a constant.
The graph passes through ( -8, 12) so substituting:
12 = a(-8)^2 - 4
12 = 64a - 4
64a = 16
a = 16/64 = 1/4.
So the equation is y = 1/4x^2 - 4.
Answer:91.1
Step-by-step explanation:
Circumference=17.6
2xπxr=17.6
2x3.14xr=17.6
6.28r=17.6
r=17.6 ➗ 6.28
r=2.8
volume of cone=(πxr^2xh) ➗ 3
Volume=(3.14x(2.8)^2x11.1) ➗ 3
Volume=(3.14x2.8x2.8x11.1) ➗ 3
Volume=273.3 ➗ 3
Volume=91.1
