A bar of gold has a volume of 722 cubic centimeters and weighs 13.949 kilograms. What's its density in grams per cubic centimete

Ahat [919]

Answer:

The density of the bar of gold is 19.32 grams per cubic centimeter .

Step-by-step explanation:

Formula

$Density = \frac{Mass}{Volume}$

As given

A bar of gold has a volume of 722 cubic centimeters and weighs 13.949 kilograms.

As 1 kilogram = 1000 gram

Than convert 13.949 kilograms into grams.

13.949 kilograms = 13.949 × 1000 grams

= 13949 grams

Mass = 13949 grams

Volume = 722 cubic centimeter

As put in the formula

$Density = \frac{13949}{722}$

Density = 19.32 grams per cubic centimeter (Approx)

Therefore the density of the bar of gold is 19.32 grams per cubic centimeter .

Find the surface area of the cylinder to the nearest tenth of a square unit. use 3.14 for pi

Alborosie

Given:

Height of cylinder is 18.2 cm
Radius of cylinder is 3 cm

$~$

To Find?

Surface area

$~$

Solution:

Using formula:

Surface area of cylinder = 2πr (h + r)

$~$

Substituting values in the formula:

$\longrightarrow \sf 2 × 3.14 × 3 (18.2 + 3)$

$\longrightarrow \sf 6.28 × 3 (21.2)$

$\longrightarrow \sf 18.84 × 21.2$

$\longrightarrow \sf 399.4 cm²$

$~$

Hence, (B) 399.4 cm² is right answer.
