Answer» given diameter of the CIRCLE = 28cm we know that diameter is double the length of it's radius. therefore length of it's radius = 28/2 = 14cm now, PERIMETER of circle is KNOWN as it's circumference. formula to find circumference of a circle is 2πr. hence, it's circumference = 2πr = 2 × 22/7 × 14 = 2 × 22 × 2 = 88CM |
