Answer:
2 28.27cm2
3If r = 6 cm, the the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm. Suppose you only know the diameter?
4Let AB be the chord of length 4 cm. C be its center
. O be the center of the circle. Join OA [OA becomes the radius]
Give n OC = 1.5 cm
AC = BC = 4/2 = 2 cm [The perpendicular drawn from the center to a chord bisect the chord]
OAC is a right angled triangle
OA2=OC2+AC2[byPythagorasTheorem]
OA2=1,52+22
=2,25+4
=6.25
OA=6.25−−−−√
OA=±2.5cm
