Answer:
Step-by-step explanation:
Surface area of cylinder = 2πr(h + r)
Volume of cylinder = πr²h
Given that S.A = Volume of the cylinder, therefore, we have:
2πr(h + r) = πr²h
Radius (r) is given as 2.5 cm
height (h) = x cm
Input the values and solve for x
2πr(h + r) = πr²h
2πr(h + r) = πr(rh)
2(h + r) = rh (πr cancels πr)
Subtract 2x from both sides
Divide both sides by 0.5
Answer:
Statement expressed by Trent is RIGHT.
Step-by-step explanation:
Here, the given expression is:
( to show) :
Now, as we know by DISTRIBUTIVE PROPERTY:
A (B + C) = AB + AC
Consider the RHS of the expression:
(p +30)(p+0) = (p +30)(p) ............ ( a + 0 = a for all a)
Simplifying (p +30)(p) by distributive property, we get:
⇒ Left side = Right side
Hence, statement expressed by Trent is RIGHT.
