Answer:
The length of its radius between 22.9 and 23.26
Step-by-step explanation:
Formula:-
Area of circle = πr² where r is the radius of circle.
It is given that, a circular disc has an area that measures between 1,650 and 1,700 square inches.
We have to find the range of radius of the circle.
there area two cases,
<u>1). For Area = 1650 inches² find radius</u>
Area = πr²
1650 = 3.14 * r²
r² = 1650/3.14 = 525.477
r =√ 525.477
r = 22.9
<u>2). For Area = 1700 inches² find radius</u>
Area = πr²
1700= 3.14 * r²
r² = 1700/3.14 = 541.401
r = √541.401
r = 23.26
Therefore length of its radius between 22.9 and 23.26
