Question

Find the circumference and area of the circle identify the radius diameter of the circle use 3.14 for pi

Answer 1

Step 1 :

In this question, we are asked to find the radius and diameter of the circle.

`\begin{gathered} \text{Radius = 5 cm} \\ \\ \text{Diameter = 2 x Radius = 2 x 5 cm = 10 cm} \end{gathered}`

Step 2 :

`\begin{gathered} \text{Circumference of the Circle = 2 }\pi r \\ =\text{ 2 x 3. 14 x 5 } \\ =31.4cm \end{gathered}`

Step 3 :

`\begin{gathered} \text{Area of the Circle = }\pi Xr^2 \\ =\text{ 3.14 x 5 x 5 } \\ =78.5cm^2 \end{gathered}`
