Find the exact area of the region bounded by two concentric circles with radii 10 inches and 6 inches.

The area of the region bonded by two concentric circles with radii 10 inches and 6 inches is in²

Step-by-step explanation:

Here, two circles having radius 10 inches and 6 inches are concentric,

Also, the area of the region bounded by these circles = Area of large circle - Area of small circle.  ( Circle having greater radius is called large circle while having smaller area is called small circle )

=

=

=

=

Hence, The area of the region bonded by two concentric circles with radii 10 inches and 6 inches is in²

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
