Question

question 8 of 10
a wheel is shaped like a circle with a diameter of 35 cm. to the nearest centimeter, what is the circumference of the wheel?

a. 220 cm
b. 110 cm
c. 55 cm
d. 70 cm

Explanation:

Step1: Recall the formula for circumference

$C = \pi d$ (where $C$ is circumference and $d$ is diameter)

Step2: Substitute the given diameter

Given $d = 35$ cm, so $C=\pi\times35$.

Step3: Approximate $\pi$ and calculate

Taking $\pi\approx3.14$, then $C\approx3.14\times35 = 109.9$ cm.

Step4: Round to the nearest centimeter

Rounding 109.9 cm to the nearest centimeter gives 110 cm.

Answer:

B. 110 cm
