Question

Sid used geometry software to draw a circle of a radius 4 units on a fgrid. He estimated the area of the circle by ciunting the squares that were mostly inside the circle and got an answer of 52 sq units. Fund the percent error in sids estimation to the nearest hundreth using the key π on your calculator..

Answer 1

Answer:

Therefore, the error is 52-50.27=1.73.

Step-by-step explanation:

We know that Sid used geometry software to draw a circle of a radius 4 units on a fgrid. He estimated the area of the circle by ciunting the squares that were mostly inside the circle and got an answer of 52 sq units.

We use the formula:

$P=r^2\cdot\pi\\P=4^2\cdot \pi\\P=50.27$

Therefore, the error is 52-50.27=1.73.
