Correct question;

Sinker is a weight used by fishermen. A fisherman uses a sinker in the shape of a sphere with radius 0.75 cm. The sinker is made of lead, which has density 11.34g/cm^3. What is the mass of the sinker?

Step-by-step explanation:

Mass of an object can be defined as

Mass m = density p × Volume V

Given;

Density of the sinker = 11.34g/cm^3

Radius of the sinker = 0.75 cm

And we know that the volume of a sphere is given as;

V = 4/3 × πr^3

Substituting r, we have;

V = 4/3 × π × 0.75^3

V = 1.767 cm^3

Then we can calculate mass as;

m = pV

m = 11.34×1.767

m = 20.03778 g

m = 20.04 grams

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
