Step-by-step explanation:
Given:
The cost of painting a circular traffic sign is $2.50 per square foot.
Diameter measures 24 inches.
Question asked:
How much rounded to the nearest cent will it cost to paint the sign?
<u>Solution:</u>
<u>First of all we will calculate the area of circular sign and then its cost:-</u>
Diameter = 24 inches
Radius, r =
<u>By unitary method:</u>
Cost of paint for 1 square foot = $2.50
As we know that 1 foot = 12 inches
Cost of paint for 12 square inches = $2.50
Cost of paint for 1 square inches =
Cost of paint for 452.57 square inches =
Cost of painting a circular traffic sign will be $94.29 (nearest cents)
You would write it 2=10(20+2)
