1) To create an equation with r isolated, you divide both sides by π and square root both (it is given that all variables are positive). The equation is √A/π = r.
2) Plugging in the numbers give us <em>√54/(22/7) = r</em>.
√54(22/7) can be rewritten as √54*7/22, which is √378/22, which can be simplified to √189/11, or about 17.18.
Answer:
11.3 cm
Step-by-step explanation:
The diagonal of the cylinder can be calculated using Pythagorean Theorem as follows:
Height of the cylinder = 8 cm
Diameter = 8 cm
Diagonal = hypotenuse = x
Thus:
8² + 8² = x²
64 + 64 = x²
128 = x²
x = √128
x = 11.3 cm
