Answers
The area of the circular ring of the fountain with a radius of 9 feet is approximately 254.34 square feet.
To find the area of the ring, we need to subtract the area of the smaller circle from the area of the larger circle. The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Therefore, the area of the larger circle is π(9^2) = 81π square feet, and the area of the smaller circle is π((9/2)^2) = 20.25π square feet.
Subtracting the area of the smaller circle from the area of the larger circle, we get:
81π - 20.25π = 60.75π
Using the approximation π ≈ 3.14, we get:
60.75π ≈ 60.75(3.14) ≈ 190.845
Therefore, the area of the ring is approximately 190.845 square feet, which is closest to option (d) 254.34 square feet.

Answer:
The other length would be 6.
Step-by-step explanation:
Rectangle area is l times height. So x is either the length for height. So we have 5 times x = 30. To find the other length we have to take 30/5 which equals 6

Answer:
The statement is true.
Step-by-step explanation:
Volume is the measurement of the space occupied by any object. Thus, mathematically, we can represent volume as the product of area and height.
Thus, we have
Volume = Area × height
Now, we know that area is measured in square units and height is in units.
Thus, we have
Volume = Square units ×units
Volume = cubic units.
Therefore, we can conclude that volume is measured in cubic units.
Thus, the statement is true.
Volume is measured in cubic units is true statement.
Volume is a measurement of the amount of space occupied by a three-dimensional object.
It is expressed in cubicunits because it involves measuring the extent of the object in three dimensions: length, width, and height.
When these dimensions are multiplied together, the result is a quantity that represents the volume of the object.
Hence, volume is measured in cubic units is true statement.
