Step-by-step explanation:
- (i) For cuboid shaped container:
(Given)
- Container is filled with water so the volume of water can be given by the following formula:
- Plugging the values of l, b and h in the above formula, we find:
- (ii) For solid right circular cylinder:
- radius (r) = a cm, h = a cm
- Formula for volume of cylinder is given as:
Answer:
-8
Step-by-step explanation:
Solving for r means that we need to isolate r from the expression.
Multiply both sides by (r +6) to 'get rid' of the fraction:
-8= 4(r +6)
Expand:
-8= 4r +4(6)
-8= 4r +24
Minus 24 on both sides:
4r= -8 -24
4r= -32
Divide both sides by 4:
r= -32 ÷4
r= -8
