3 \frac {3} {4} -1 \frac {3} {14} =

To do this, we convert the mixed numbers to improper fractions:

\frac {4 * 3 + 3} {4} - \frac {14 * 1 + 3} {14} =\\\frac {15} {4} - \frac {17} {14} =\\\frac {14 * 15-4 * 17} {4 * 14} =\\\frac {210-68} {56} =\\\frac {142} {56} =\\\frac {71} {28} =\\2 \frac {15} {28}

Answer:

\frac {71} {28} = 2 \frac {15} {28}

A sphere has a diameter of 0.926 inch what is the volume of the sphere use 3.14 for Pie
lord [1]

Answer:

The volume of the sphere is 0.415\ \text{inch}^3.

Step-by-step explanation:

The diameter of a sphere is 0.926 inch. It is required to find the volume of the sphere. The formula used to find the volume of sphere is given by :

V=\dfrac{4}{3}\pi r^3

Since, r is radius, r = d/2 = 0.463 inch

So,

V=\dfrac{4}{3}\times 3.14\times (0.463)^3\\\\V=0.415\ \text{inch}^3

So, the volume of the sphere is 0.415\ \text{inch}^3.
