Answer: 12 inches

Step-by-step explanation:

Given: In a circle , the area of a sector = 36 \pi\text{ inches}

Measure of Arc \theta=90^{\circ}

The formula to calculate the area of the sector is given by:-

\text{ Area of sector}=\frac{\theta}{360^{\circ}}\times\pi r^2

Substitute area and angle in the formula, we get

36\pi=\frac{90^{\circ}}{360^{\circ}}\times\pi r^2\\\\\Rightarrow36\pi=\frac{1}{4}\times\pi r^2\\\\\Rightarrow\ r^2=36\times4\\\\\Rightarrow r^2=144\\\\\Rightarrow\ r=12\ \text{ inches}

Hence, the radius of the circle = 12 inches.
