V = 4/3r3. A sphere has a radius of 3.5 inches. Volume (to the nearest tenth) =
1 answer:
The correct formula of volume of sphere is:
Where r is the radius of sphere.
Given, r = 3.5 inches.
So, first step is to plug in r = 3.5 in the above formula to get the volume: V. Hence,
Since, π = 3.14
= 1.33333 * 3.14 * 42.875
= 179.5028846
= 179.5 Rounded to nearest tenth.
So, volume of sphere is 179.5 cubic inches .

Answer:
Step-by-step explanation:
First, we need to find the common denominator
The easiest way to do this is by multiplying the two given denominators, which are 2 and 5.
2 × 5 = 10
So, our common denominator is 10. Then, multiply the numerators of the two fractions by 2 and 5. Here's why:
=
We multiplied the top and bottom by 2 to make sure our new fraction stays equivalent to the original fraction.
Do the same thing for the other one:
=
Finally, subtract the two fractions to find the difference between the two times:
=
The reason we used the common denominator is because we can only add or subtract fractions if they have the same denominator.
