Answer:
.
Step-by-step explanation:
The volume of a cone is 84.78 cm
<u>Step-by-step explanation</u>:
<u>Given</u>:
radius = 3 cm and
height = 9 cm
<u>To Find</u>:
The Volume of a Cone
<u>Formula</u>:
The Formula for the volume of a cone is
V=πr2 *h/3
<u>Solution</u>:
V=πr2 *h/3
π value is 3.14
V= 3.14*(3)^2*9/3
V=3.14*9*3
V= 84.78 cm
Therefore the volume is 84.78 cm.
First, factor each expression by finding two terms whose product is equal to the c term and sum is equal to the b term.
x^2-x+6 --> (x-3)(x+2)
x^2-4 --> (x+2) (x-2)
Next, cancel the terms that are equal on the top and bottom.
You are left with the answer of:
