Answer:
42
Step-by-step explanation:
the ratio of x to y is 1 to 3.5
12x3.5=42
Answer:
-3x and -6x
Step-by-step explanation:
just multiply
V=hpr^2
V=10p(12/2)^2
V=360p cm^3 exact
V=1131 cm^3 (to the nearest tenth of a cubic centimeter)
Answer:
8pi units³
Step-by-step explanation:
Volume of the solid
= pi × integral of y².dx
= pi × integral of x
pi × [x²/2]
Limits are x = 2 and x = 6
pi × [6²/2 - 2²/2]
pi × (18 - 2)
= 16pi units³
Since the solid is only above the x-axis half of this volume would be generated:
½ × 16pi = 8pi units³
10^-8 because e-8 is 10^-8
