Answer:

Radius could be 23 inches

Step-by-step explanation:

It is given that, a circular disc has an area that measures between 1,650 and 1,700 square inches.

Area of circular disc is,
$A=\pi r^2$

r is the radius of circular disc

When the area of circular disc is 1650, then its radius is given by :

$A_1=\pi r_1^2$

$r_1=\sqrt{(1650)/(3.14)} =22.92\ inches$

When the area of circular disc is 1700, then its radius is given by :

$A_2=\pi r_2^2$

$r_2=\sqrt{(1700)/(3.14)} =23.27\ inches$

So, the radius of circular disc could be :

22.92 inches ≤ r ≤ 23.27 inches

Hence, the radius of circular disc could be 23 inches
