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

$\begin{gathered} \text{ Area of lid =}\Pi Radius^2 \\ \text{Area of lid =}\Pi\times3.2^2 \\ \text{Area of lid =}3.14\times3.2\times3.2 \\ \text{Area of lid=}32.17in^2 \end{gathered}$

Area of lid is 32. 17 in²
