Question

Is the diameter of the closed paint can lid is 6.4 in what is the lids area in inches squared

Answer 1

The lid is in the shape of circle, with the diameter 6.4 inches

Diameter = 2 Radius

Radius = 1/2 Diameter

Radius = 1/2 x 6.4

Radius = 3.2 inch

The area of circle with radius r is :

`\text{ Area of circle =}\Pi Radius^2`

Substitute the value of the radius = 3.2 inch

`\begin{gathered} \text{ Area of lid =}\Pi Radius^2 \\ \text{Area of lid =}\Pi*3.2^2 \\ \text{Area of lid =}3.14*3.2*3.2 \\ \text{Area of lid=}32.17in^2 \end{gathered}`

Area of lid is 32. 17 in²
