Sagot :
Answer:
Step-by-step explanation:
[tex]C =2\pi r[/tex] and since we have to state the answer to 2 decimal places, that means that we are using the number value for π. In specific, π = 3.1415 is good enough. The other thing we note is that the formula for circumference could also be written in terms of its diameter as opposed to its radius:
C = πd. Let's use that one since we are given the diameter of the tire, not the radius.
C = (3.1415)(.65) so
C = 2.04 m
The circumference of the wheel is C = 2.04 m.
What is area of the circle?
- Area of a circle is the region occupied by the circle in a two-dimensional plane.
- It can be determined easily using a formula, A = πr2, (Pi r-squared) where r is the radius of the circle.
- The unit of area is the square unit, such as m2, cm2, etc
Given ,
d = 0.65 m
π = 3.14
Let's use that one since we are given the diameter of the tire, not the radius.
Use this formula , C = πd
C = (3.1415)(.65)
so, C = 2.04 m
Therefore, the circumference of the wheel is C = 2.04 m.
