The measurement of the circumference of a circle is found to be 68 centimeters, with a possible error of 0.9 centimeter. (a) approximate the percent error in computing the area of the circle. (round your answer to two decimal places

2.65%

Step-by-step explanation:

Given : The  measurement of the circumference of a circle =  68 centimeters

Possible error : centimeter.

The formula to find the circumference :-

Differentiate the formula of circumference w.r.t. r , we get

The area of a circle  :-

Differentiate both sides w.r.t r, we get

The percent error in computing the area of the circle is given by :-

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
