Answer:
The area of a circle with a diameter of 10 inches is 78.5 in².
Step-by-step explanation:
1. Know the formula for finding the area of a circle.
A = r²[tex]\pi[/tex]
2. Since you need the radius for finding area, you will need to divide 10 by 2 because the radius is half of the diameter.
10 ÷ 2 = 5
3. Add in your numbers to the formula.
A = (5)²[tex]\pi[/tex]
4. Simplify the equation. We can use 3.14 for pi.
A = 25[tex]\pi[/tex]
A = 78.5
So, the area of the circle is 78.5 in².
Answer:
The area is 78.54
a=pi(r squared) since the diameter is 10 inches and the radius is 1/2 of the diameter so the radius is 5.
a=3.14(5x5)
a=3.14(25)
a=78.54
