2 pi/3

Step-by-step explanation:

Since the arc length is 1/3 of the circumference of a circle, the measure of the central angle is 1/3 of the whole circle, or 1/3(2 pi) = 2 pi/3

The radius of can is approximately 3.82 cm.

Step-by-step explanation:

We are given the following in the question:

Surface area of can = 332 square cm

Height of can = 10 cm

We have to find the radius of circular top.

Formula:

Surface area of can = Surface area of cylinder

$2\pi r(r + h) = 332\\2\pi r(r + 10) = 332\\\\r^2 + 10r = \dfrac{332}{2\pi}\\\\r^2 + 10r - 52.82 = 0\\\text{Using quadratic formula}\\\\r = \dfrac{-10\pm \sqrt{100 - 4(-52.82)}}{2}\\\\r = -13.82, 3.82$

Since, the radius cannot be negative.

The radius of can is approximately 3.82 cm.
