Error Analysis Clara is asked to find the surface area of a sphere which has radius r. of 14 in. She says the surface area is 175.84 in?
What is Clara's likely error? Use 3.14 for pie.
(Type an integer or decimal rounded to the nearest hundredth as needed.)
Clara's likely error is that she forgot to square the radius when calculating the surface area of the sphere.
The correct formula for calculating the surface area of a sphere with radius r is given by:
Surface Area = 4 * π * r^2
Using the given value of r = 14 in and the value of π = 3.14, we can calculate the correct surface area:
Surface Area = 4 * 3.14 * (14)^2
= 4 * 3.14 * 196
= 2460.64 in^2
So, Clara's likely error is that she did not square the radius of 14 inches when calculating the surface area.
