The reason why is because, the student's grade is falling dramatically while they watch TV. So therefore, we can erase A and D. B maybe however, it isn't "weak" but it is a heavy decrease. Therefore, your answer would be C.

The value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x.

zlopas [31]

Answer:

$x = 2.5$

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)

$2(x + 2.5) = 2.5*x$

$2x + 5 = 2.5x$

Subtract 2x from both sides

$2x + 5 - 2x = 2.5x - 2x$

$5 = 0.5x$

Divide both sides by 0.5

$\frac{5}{0.5} = \frac{0.5x}{0.5}$

$2.5 = x$

$x = 2.5$
