Consider we need to find the equation of the circle.
Given:
The Center at (-4,-1), radius = 2.
To find:
The equation of the circle.
Solution:
The standard form of a circle is
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting h=-4, k=-1 and r=2, we get
Therefore, the equation of the circle is .
The answer is .52 9/16 2/3
Answer:
$94.29 (nearest cents)
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)
