Answer:

20569.09 mm³

Step-by-step explanation:

This requires the use of the formula to find the volume of a sphere.

r = radius = 17mm

V = 4(πr³)/3

V = 4(3.14*17³)/3

V = 4(3.14*4913)/3

V = 4*15426.82/3

V = 61707.28/3

V = 20569.09333

Therefore the volume of the marble is about 20569.09 mm³

Need help asap. Simplify the expression 6/c+4/c^2 show work

Zina [86]

By taking a common denominator, we can find out that the simplified expression of the given expression is $\frac{6c+4}{c^{2} }$ .

The given expression is -

$\frac{6}{c}+\frac{4}{c^{2} }$ ---- (1)

We have to simplify the expression.

From equation (1), we have the given expression as -

$\frac{6}{c}+\frac{4}{c^{2} }$

Establishing common denominator $c^{2}$ , we have

$\frac{6c}{c^{2} }+\frac{4}{c^{2}}$

Combining the numerator and common denominator, we have

$\frac{6c+4}{c^{2} }$

Thus, the simplified expression of the given expression is $\frac{6c+4}{c^{2} }$ which is obtained by taking a common denominator.
