Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer
Step-by-step explanation:
Given
Diameter of Cone = d = 6 cm
Radius will be:
r = d/2 = 6/2 = 3 cm
Height of cone = h = 3d = 18 cm
The volume of cone is given by:

Putting the values

Hence,
Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Answer:
sq rt of 66 is 8.12 so 8.1 closest
Answer: 21 cm is the volume
Step-by-step explanation: multiply 7cm x3 cm
Since the slope is -2 we know that m=-2. Now use the standard form of y=mx+b and plug in the coordinates (-8,2). We know y=2, x=-8, and m=-2. Therefore we get 2=-2(-8)+b. Now solve for b and you get -14. Therefore, the equation is y=-2x-14.
