Answer:
your answer for 11/4+11/2 would be 8.25
Step-by-step explanation:
answer
given
v=2100cm³
h=3r
v=1/3πr²h
soln
v=1/3πr²h
2100cm³=1/3×π×r²×3r( you will insert 3r in the place of h.)
2100cm³=3π/3×r³(cancel 3 by 3)
2100cm³= πr³
r³=2100cm³/3.14 ( π=3.14)
¾r³=¾2100cm³/3.14(I make them cube root.sorry I can't use the real cube root so I replace it by ¾)
r=8.74…
Step-by-step explanation:
area of a rectangle=l*w which is 40*14=560
area of a square=30^2=900
900+560=1460
The answer is 66.
66 * 3 = 198
66 * 5 = 330
