Question

A circular disc has an area that measures between 1,650 and 1,700 square inches. What could be the length of its radius? Use 3.14 for . 23 in. 24 in. 25 in. 26 in.

Answer 1

Answer:

23 in

Step-by-step explanation:

We know the area of the circular disc is A = πr² where r = radius and π = 3.14.

So, r = √(A/π)

Now, if A = 1650 square inches,

r = √(A/π)

= √(1650 in²/π)

= √525.48 in²

= 22.92 in

≅ 22.9 in

Also, if A = 1700 square inches,

r = √(A/π)

= √(1700 in²/π)

= √541.40 in²

= 23.27 in

≅ 23.3 in

If the area is between 1650 in² and 1700 in², that is 1650 in² < A < 1700 in²

then, the radius is between 22.9 in < r < 23.3 in.

Since the left and right side of the inequality are approximately 23 in, the radius of the circular disc is 23 in.
