Answer:
D
Step-by-step explanation:
They created ratios so people could get information.
When finding the volume of a cube, you would multiply the length x width x height. To find the volume, you would cube the length of one of the sides. For this problem, think of it as working backward because you're starting with the volume but need to know the length of a side. To do the opposite (or inverse) of cubing, you would instead find the cube root of the volume. The cube root of 3,944.312 cubic cm would give you 15.8 cm.
The formula for the volume of a cylinder is <em>v =
. </em>Take the numbers you are given in the problem and put them into the equation to get: <em>v +
. </em>After calculation this equation, you will get an answer of 160.8495. Just round to the nearest tenth to get 160.8.
Answer:
7 dollars
Step-by-step explanation:
Looks like the larger triangle is equilateral (well, it must be, otherwise finding the area is impossible). That means the inradius is 6 and the outradius is 12, which is to say the altitudes (equal to the height, in this case) of this triangle have length 6 + 12 = 18.
In the smaller right triangle, the length of the missing leg is half the base of the larger triangle; call this length By the Pythagorean theorem,
Then the area of the larger triangle is
