Volume (denoted 'V') of a sphere with a known radius (denoted 'r') can be calculated using the formula below:

V = 4/3(PI*r3)

In plain english the volume of a sphere can be calculated by taking four-thirds of the product of radius (r) cubed and PI.

You can approximated PI using: 3.14159. If the number you are given for the radius does not have a lot of digits you may use a shorter approximation. If the radius you are given has a lot of digits then you may need to use a longer approximation.

Here is a step-by-step case that illustrates how to find the volume of a sphere with a radius of 5 meters. We'll u

Predict if the product will be greater than, less than or equal to the second factor 4/5 x 1 2/5 = y
Radda [10]

Answer:

The product will be less than the second factor.

Step-by-step explanation:

Given the expression

\frac{4}{5}\:\times \:1\frac{2}{5}\:=y

solving to determine the product value

y=\:\frac{4}{5}\times \:\:1\frac{2}{5}

  =\frac{4}{5}\times \frac{7}{5}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

  =\frac{4\times \:7}{5\times \:5}

  =\frac{28}{5\times \:5}

  =\frac{28}{25}

As the value of the second factor is:

1\frac{2}{5}=\frac{7}{5}=1.4

And the product value is:

y=\frac{28}{25}=1.12

It is clear that the product value 'y = 1.12' is lesser than the second factor value '1.4'.

i.e. 1.12 < 1.4

Thus, the product will be less than the second factor.
