Josiah is shopping for a tablecloth for a circular table with a radius of 18 inches. He claims the area is 113.04 square inches. What statement BEST explains his claim?
The circumference, not the area, was calculated. The correct approximate area is about 4,069 square inches.
The circumference, not the area, was calculated. The correct approximate area is about 1,017 square inches.
The diameter should be used for all calculations. The correct approximate area is about 4,069 square inches.
The diameter should be used for all calculations. The correct approximate area is about 1,017 square inches.
The correct answer is: The circumference, not the area, was calculated. The correct approximate area is about 1,017 square inches.
This is because Josiah likely used the formula for the area of a circle (A=πr^2) when calculating the area, but mistakenly used the radius instead of the diameter. To find the correct area, he should have used the diameter (36 inches) in the formula. The correct area would then be approximately 1,017 square inches.
