Question

Area of circular cross section A-962.5 square mm . Find out the diamater "d"

Answer 1

Answer:

35 mm

Step-by-step explanation:

area of circular cross section,A=962.5 mm^2

area of circular cross section, A = πr^2

962.5 = (22/7)/r^2

r^2 = 306.25

r = √(306.25

r = 17.5 mm

diameter, d=2r = 2×17.5

d=35 mm
