The volume of the bedroom is 11 x 10 x 10 = 1100 cubic feet.
The volume of the den is double, so 1100 x 2 = 2200 cubic feet.
Divide the volume of the den by the height, since it is the same as the bedroom, this will give you the area:
2200 / 10 = 220 square feet.
Two sets of numbers that could equal 220 are 22 x 10 or 22 x 11
The room can be 20 ft by 10 ft or 22 ft by 11 ft and the volume is 2200 cubic feet.
Answer:
615 centimeters
Step-by-step explanation:
Kate used 6.15 meters of ribbon to make a bow
The centimeters of the ribbon used by kate can be calculated as follows
1 meter=100 centimeters
6.15 meters= x
Cross multiply both sides
1 × x = 6.15 × 100
x = 615 centimeters
Hence Kate used 615 centimeters of the ribbon

The circumference of the outer circle is greater than that of the inner circle by 18.86 feet.
<h3>What is Circle?</h3>
A circle is a round 2-dimensional shape. It is a closed shape with a distance from center to circumference termed as radius 'r' and distance from one point on the circumference to another point passing through center termed as diameter 'd'.
The circumference of the inner circle is 88 ft.
Circumference of a Circle = 2πr
2πr = 88
2 X 22/7 X r = 88
r = 88 X 7 / 44
r = 14 ft.
Radius of the inner circle = 14 feet
If the distance between the inner circle and the outer circle is 3 ft, the radius of the outer circle = 14+3 = 17 feet.
circumference of the outer Circle = 2πr
= 2 X 22/7 X 17
= 106.86 ft.
Difference in Circumference = 106.86 - 88 = 18.86 feet
Thus, the circumference of the outer circle is greater than that of the inner circle by 18.86 feet.
