We have the function C(r) = 6.28r.
When we enter an input into the function, we get a number multiplied by 6.28.
When we plug in a value, replace all variables with the number you entered.
C(4) = 6.28(4)
C(4) = 25.12
So, 25.12 is the answer.

Answer:
7.1 m
Step-by-step explanation:
A cube has 6 congruent square faces.
Given the surface area = 302.46 m² then the area of one face is
302.46 ÷ 6 = 50.41 m²
The area of a square = s² ( s is the side length ), thus
s² = 50.41 ( take the square root of both sides )
s = = 7.1 m
The length of each side of the cube is 7.1 m
Answer:
790
Step-by-step explanation:
.10x=79
multiply both sides by 10
x=790
Answer:
Area=11,309.73
Step-by-step explanation:
area of a circle is πr^2 so half of the diameter is the radius so it's 60.
pi x 60^2= 11,309.73
