Answer:
The answer to your question is Circumference = 20π cm; Area = 100π cm
Step-by-step explanation:
Data
diameter = 20 cm
Circumference = ?
Area = ?
Process
1.- Write the formula of Circumference
Circumference = πd
-Substitution
Circumference = 20π
2.- Write the formula of area of a circle
Area of a circle = πr²
-Calculate the radius
radius = diameter/2
radius = 20/2
= 10 cm
-Substitution
Area = (10)²π
-Result
Area = 100π
The sqft for an area that is 12 by 25 is 300.
2.60 x 300 = 780
It would cost $780.00.
Hope it helps!
You have to do 7,800 divide by 12 and you get D) 650.
