This may be calculated from its diameter using the formula:
<= ad or
Or, substituting the radius for the diameter:
C= 2tr
Wherer is the radius and d is the diameter of the circle, and it (the Greek letter pi) is the constant 3.141
592

Hint:ci

The radius of the circle is 4 cm and the measure of the central angle is 90° the area of the sector with a central angle measuring 90° and radius of length 4 cm is vt cm the triangle in the sector is 4 cm the area of the triangle is v/cm² the area of the segment of the circle is (471 - ) cm?
