Asliver of gold has a volume of 0.678 cm3. what is the mass of this sliver of gold?

Answer - 13.098 gm

Description -

Dear student,

As we know

⇒ Mass = Density * Volume

so multiplying given Volume with the Density of gold ,we can calculate the mass of the gold . Density of gold at room temp. is 19.32 grams per cubic centimeter.

so mass of the sliver of gold = 19.32 * 0.678 = 13.098 (ans)

where r the answers

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
