Answer:
The answer is = 93.32cm
Step-by-step explanation:
The height and radius are equal of this cylinder
[tex]s = 2\pi \: r(r + h)[/tex]
(The surface area of the cylinder)
=
[tex]2\pi \: r(r + h)[/tex]
2772= 2× 344×r×2r ( s=2772 Given)
[tex] {r}^{2} = \frac{2772}{2 \times 344 \times 2} [/tex]
[tex] = 2207[/tex]
[tex]r = \sqrt{2207} \\ = 14.86cm[/tex]
[tex]c = 2\pi \: r(the \: circumfrence \: formule)[/tex]
[tex] = 2 \times 3.14 \times 14.86[/tex]
[tex] = 93.32(cm)[/tex]
Answer:
131.9 cm
Step-by-step explanation:
h = r
Lateral area of cylinder: 2πrh
Since r = h, the lateral surface area = 2πr²
2πr² = 2772
r² = 2772/(2π)
r² = 441.2
r = 21 cm
circumference = 2πr
circumference = 2π(21 cm)
circumference = 131.9 cm
