Harold uses a cone shaped feeder, with a diameter of 7.5 centimeters and a height of 3.5 centimeters, to feed his tropical fish. How many cubic centimeters of feed can this feeder hold? Use 3.14 for pi. Enter your answer in the box as a decimal rounded to the nearest tenth
2 answers:
This requires you to find the volume of the cone. The volume of a cone is 1/3 the area of the base (a circle) times the height of the cone, or 1/3(3.14)r^2 * h. The radius of the base is 7.5/2 or 3.75. V = 1/3(3.14 * 3.75^2) * 3.5 V = 1/3(44.16) * 3.5 V = 1/3*154.56V = 51.5 cm^3 of feed
Answer:
Step-by-step explanation:
step 1
Find the volume of a cone
we know that

Answer:
Step-by-step explanation:
if additive inverse then
(1/3y)+7
if multiplicative inverse then
3y-7
if both then
3y+7
if in this way
f(x)=(1/3x)-7
f(-x)=(-1/3)-7
