Answer:
V = 577 cubic cm
Step-by-step explanation:
V(cyl) = Area of Base x Height
Area of Base = πr²
r = 7/2 or 3.5
h = 15
V = π(3.5)²(15)
V = 577
Answer:
z ∝ x^2
Z = kx^2
when z = 36 and x = 2, substitute into the equation above
i.e, 36 = k x 2^2
36 = 4k
therefore k = 9
so the equation becomes
Z = 9x^2
when x =3
Z = 9 x 3^2
Z = 9 x 9
Z = 81
