Answer:
The answer is 390 × pi.
Step-by-step explanation:
Big cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 9^2 x 15
= 1272.3 cubic inches
Small cone:
V = 1/3 x pi x r^2 x h
= 1/3 x 3.14 x 3^2 x 5
= 47.1 cubic inches
1272.3 - 47.1 = 1225.2 cubic inches
1272/3.14 ≈ 390
The answer is 390 × pi.
Answer:
A. No, the estimate should be higher
Step-by-step explanation:
To determine the maximum number of gallons of fuel the car can consume, we express this as;
Maximum miles driven=highest consumption per gallon×Maximum gallons
where;
Maximum miles driven per person=64 mile
Maximum miles driven=64×4=256 miles
highest consumption per gallon=24.56 miles per gallon
Maximum gallons=g
replacing;
256=24.56×g
24.56 g=256
g≥256/24.56=10.42 gallons
g≥10.42 gallons
No, the estimate should be higher
<span>F for Frank, A or Alice.
F(initial)=1.95 inches
A(initial)=1.50 inches
Frank's equation at .25 inches per year and t representing year variable.
F=1.95+.25t
Alice's equation at .40 inches per year and t representing year variable.
A=1.5+.40t
To figure out how old they will be when their beaks are the same lengths set the equations equal to eachother as the equations are length.
1.95+.25t=1.5+.40t
.45=.15t
t=3 years</span>
I think the first one is
x<3
And the second one is
x<2
