The equation san be used to calculate the density, d, of an object with mass, m, and volume, v. which is an
equivalent equation solved for v?

v=d/m

Step-by-step explanation:

volume is the division between the distance and the mass

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

1/4 is the answer if i recall correctly.
