Step-by-step explanation:

Given that,

The area of sector, A = 17.45 cm²

Radius, r = 5 cm

We need to find the angle in the given sector. The area of a sector is given by :

Where

is the angle of sector

So, the angle of sector is .

First, we must find the length and width of the stone.  To do this, divide the area by the side that we know.  7/10*5/4  This comes to 7/8, the other side length.  Adding 7/8 and 5/4 together and multiplying by two gives us the perimeter.  This comes out to 17/4, or 4 and 1/4 inches.  Therefore, 3.5 inches of wiring would not be enough.  Please mark Brainliest!!!
