Answer:
18
Step-by-step explanation:
The height of the cone is 8, and the diameter is 3. This means that the radius is 3/2, or 1.5. We can plug everything into the formula (using 3 for pi):

We can cancel out the 3 from the numerator and the denominator, so we are left with 1.5^2 times 8. 1.5 squared is equal to 2.25, and 2.25 times 8 is equal to 18.
Answer:
4
Step-by-step explanation:
27-6=21 1
21-6=15 2
15-6=9 3
9-6=3 4
We can use the rule of three to figure out what's 5% of 79:
100/79=5/x
x= (79*5/100)=3.95
Let's add said 5% to 79:
79+3.95=82.95
