The diameter of a wheel on harrys bicycle is 0.65m calculate the circumference of the wheel give your answer correct to 2 decimal places

[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.
