Answer:
26.8 pi or approx. 84.19
Step-by-step explanation:
Circumference can be found by multiplying the diameter by pi. The diameter is twice the radius, which in this case is 13.4, so it's 13.4 * 2 = 26.8.
Multiply by pi, and you've got your answer!
V=4/3 π •r^3 multiply both sides with 3
3•36π=4π • r^3
108 π=4 π • r^3
r^3 =108 π/4 π
r=3 inch

Ok so since we don't know how many cubes are covered, I will solve for how much area was covered on 1 cube
cube has 6 faces, all squares
area of square=side^2
therefor surface area (area covered by carmael)=6 times side^2
side=1 and 1/3
convert 1 and 1/3 to imporoper
1 and 1/3=1+1/3=3/3+1/3=4/3
Surface Area=6 times side^2
SA=6(4/3)^2
SA=6(16/9)
SA=96/9
SA=10 and 6/9
SA=10 and 2/3
answer is 10 and 2/3 in^2 is covered per cube
(if you are given a number of cubes, multiply 10 and 2/3 in^2 by number of cubes)
