Answer:

0.14594 g/cm³

Explanation:

Density = Mass / Volume

Mass = 5400 g

Volume = 0.37 m³

Density = M /V

volume = 0.37 m³ = 37000 cm³

Density = $\frac{5400}{37000}$

= 0.14594 g/cm³

adelina 88 [10]

The circumference of a circle is (pi) x (diameter)

The circumference of the cupcake is (pi) x (5 cm)

Halfway around is (1/2) x (pi) x (5 cm) = (2.5 pi cm) = <em>about 7.85 cm</em>

The 'why' appears up above, in the first 2 lines of this solution.
