Answer:
12.78 units
Step-by-step explanation:
The formula for arc length =
2πr × θ/360
From the question:
θ = 122°
r = 6 units
Therefore, the arc length =
2 × π × 6 × (122/360)
= 12.775810125 units
Approximately to the nearest hundredth = 12.78 units
Therefore, the length of arc CE is 12.78 units

Step-by-step explanation:
It is given that,
An aquarium is in the shape of a rectangular prism. The area of the base of the aquarium is 250 square inches.
We need to find the volume of the aquarium.
The formula for the volume of the rectangular prism is given by :
V = lbh
Where, l is length, b is width and h is height
Let the height of the prism is h inches. So,
V = A × h (As Area, A = lb)
V = 250× h
= (250h) inch³
By substituting the value of h, we can find its volume.
Hence, the volume of the aquarium is (250h) inch³.
