Answer:

We can use the formula for the area of a sector of a circle:

A = (θ/360) x πr^2

where A is the area of the sector, θ is the central angle of the sector in degrees, and r is the radius of the circle.

In this case, we know that the central angle of the sector is 70° and the area of the circle is 169π square inches. We can use the area of the circle to find the radius:

A = πr^2

169π = πr^2

r^2 = 169

r = 13

Now we can use the formula for the area of the sector:

A = (θ/360) x πr^2

A = (70/360) x π(13)^2

A = (7/36) x 169π

A = 29.5π square inches

Therefore, the area of the sector is approximately 29.5π square inches.
