The mass of the rock is 3020.27 grams , if a rock is in the shape of a sphere with a radius of 5.08 centimeters and the rock has a density of 5.5 grams per cubic centimeter,
Step-by-step explanation:
The given is,
Radius of the rock is 5.08 cm (Sphere)
Density of rock 5.5 grams per cubic centimeters
Step:1
Formula for volume of sphere,
..........................(1)
Where, r - Radius of sphere
From the given values,
r = 5.08 cm
Equation (1) becomes,



V = 549.14 cubic centimeters
Step:2
Mass of rock = Volume of rock × Density of rock
= 549.14 × 5.5 ( ∵
)
= 3020.27 grams
Mass of the rock = 3020.27 grams
Result:
The mass of the rock is 3020.27 grams , if a rock is in the shape of a sphere with a radius of 5.08 centimeters and the rock has a density of 5.5 grams per cubic centimeter,

"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like
.
A binomial has 2 terms like 
A trinomial has 3 terms like 
And a polynomial has 4 or more terms.
So basically one can classify the type of polynomial by counting the number of terms in a given equation.
