Answer:
Step-by-step explanation:
Factor 16 using prime factorisation:
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
⇒ 16 = 2⁴
Substitute 16 for 2⁴:
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
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
4. Simplify the equation. We can use 3.14 for pi.
A = 25
A = 78.5
So, the area of the circle is 78.5 in².
