My frnd ur answer us here. mark brainliest if it is helpful.

Step-by-step explanation:

There are 12 hours and 360 degrees which implies one hour of time rotates hour hand by 30 degrees

In 90 minutes of time , (3/2 hour) the hour clock moves (30 + 30/2) i.e 45 degree.

Area of sector of angle x is x/360 * π* (r^2)

so area of sector is 45/360 * π * 36 = 14.13cm²..
