Answer:

-57

Step-by-step explanation:

log \frac{ {c}^{7} }{ {a}^{6} {b}^{2}  }  \\  \\  = log {c}^{7}   - log( {a}^{6} {b}^{2} )  \\  \\  = log {c}^{7}   - (log {a}^{6} +  log{b}^{2} )\\  \\  = 7 \: log {c}   - (6 \: log {a}+  2 \: log{b})\\  \\  = 7 \:( - 9) - [6 \: ( - 5)+  2 \: (12)] \\  \\  =  - 63 - [ - 30 + 24] \\  \\  =  - 63 - [- 6] \\  \\  =  - 63 + 6 \\  \\  =  - 57

A gum ball has a radius that is 30mm. The radius of the gumballs spherical hollow core is 28mm. What is the volume of the gum ba
Arada [10]

Answer:

V = 21145.01 mm³

Step-by-step explanation:

Given that:

The radius of the gumball = 30  mm

The radius of the spherical hollow-core = 28 mm

Consider the radius of the gumball to be r_2 and the radius of the spherical hollow-core to be r_1. Then;

The volume of the gumball can be determined by using the formula of a sphere.

V = \dfrac{4}{3}\pi (r_2^3 - r_1^3)

V = \dfrac{4}{3} \times \pi \times (30^3 - 28^3)

V = 21145.01 mm³
