1) Find the AREA of this circle with a radius of 5. (Use formula: A = pi x r^2. Use 3.14 for pi.)
*
A = 3.14 x 5^2 = 78.5 square units.
To find the area of a circle with a radius of 5, we can use the formula A = πr^2, where A represents the area and r represents the radius.
Given that the radius is 5, we can substitute r = 5 into the formula:
A = 3.14 x (5)^2
Now, we can simplify the expression:
A = 3.14 x 25
Finally, we can calculate the area:
A = 78.5
Therefore, the area of the circle with a radius of 5 is 78.5 square units.
