Question

find the missing measurements for each circle. you can use 3.14 as an approximation for pi. circle t has a circumference of 76 cm. what is the approximate length of the radius and the diameter? 4) circumference (cm) 76 diameter (cm) blank radius (cm) blank

Explanation:

Step1: Recall the formula for the circumference of a circle

$C = \pi d$, where $C$ is the circumference and $d$ is the diameter.

Step2: Solve for the diameter

Given $C = 76$ cm and $\pi\approx3.14$. We can rewrite the formula as $d=\frac{C}{\pi}$. Substituting the values, we get $d=\frac{76}{3.14}\approx24.20$ cm.

Step3: Recall the relationship between radius and diameter

$r=\frac{d}{2}$, where $r$ is the radius and $d$ is the diameter.

Step4: Calculate the radius

Since $d\approx24.20$ cm, then $r=\frac{24.20}{2}=12.10$ cm.

Answer:

Diameter: $24.20$ cm
Radius: $12.10$ cm
