Answer: 117.226666667 cm^3
Step-by-step explanation:
So, we all know the formula for working out the volume of a cone is
V= 1/3πr^2h
V = 1÷3 x 3.14 × r^2 x h
The radius is half the diameter. Your diameter is 8 so the radius would be 4. And 7 is your height by the way.
So let's plot it all in!
V= 1÷3 x 3.14 × 4^2 x 7
V = 117.226666667cm^3
Round to the nearest 10 = 117.2cm^3
To the nearest 100 = 117.23cm^3
To the nearest whole number = 117cm^3

Answer:
So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.
Step-by-step explanation:
The height h of the ball is modeled by the following equation
The problem want you to find the times the ball will be 48 feet above the ground.
It is going to be when:
We can simplify by 16t. So
It means that
16t = 0
t = 0
or
t - 2 = 0
t = 2
So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.
