How do you find diameter using rotations and distance?
Rotations and distance tells you about the circumference and this tells you about the diameter. How about a specific problem?
Find the perimeter of a semicircle of diameter 10cm?
First find the circumference of the whole circle using Pi x diameter. Halve the answer and add the diameter. Thus: 3.1416 × 10 = 31.416 ÷ 2 + 10 = 25.708cm So the perimeter of the semi-circle is 25.7cm
