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.
Answer: 7^5 or 7 to the fifth power.
Step-by-step explanation: This is an exponent meaning you count the 7’s and in the first picture there’s 5 7’s. This means that the number your putting to a power is the yellow box so that’s 7 and the exponent is 5 not 4 because if you did 7 to the first power it’s still 7 so it would be 7 to the 5th power or 7^5
