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
Answer:
4
Step-by-step explanation:
x - length of side of larger hexagon
y - length of side of smaller hexagon
We know that,
x/y = 
y = 
Hence,
perimeter of = 
* perimeter of smaller hexagon
larger hexagon
=
