1. A tank is 3/5 full of water. After 330 litres of water is drawn out, it becomes 2/7 full. Find the capacity of the tank in litres.

1050

Step-by-step explanation:

Let x = full capacity

Move the variable to the left side by subtracting both sides by

Combine the like terms (don't forget about common denominator)

Multiply both sides by to isolate the x

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
