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:
x= 0.4
Step-by-step explanation:
We need to solve and find the value of x
7 1/3x = 1.6 ÷ 6/11
Converting mixed fraction into improper fraction
22/3 x = 1.6 ÷ 6/11
Converting ÷ sign by X and reciprocating the term
22/3 x = 1.6 * 11/6
Now divide both sides by 3/22
x = 1.6 * 11/6 * 3/22
x = 1.6 * 1/2 * 1/2
x = 1.6/4
x = 0.4
S0, x= 0.4
