Question

radius of a circle is 50000 micron. find (a) its area units of m2 and (b) its circumference in units of meter

science physics

Answer 1

Answer #1

1micron = 10^-6m

R= 50000 x 10^-6m= 5 x 10^-2= 0.05m

Area = pi x R^2= 3.14 x 0.05 x0.05 = 0.00785m^2

Circumference = 2 x pi x R= 2x 3.14 x 0.05 = 0.314m
