The perimeter of a semicircle is 17.476 centimetres. What is the semicircle's diameter?
Question
Solution 1
The perimeter of a semicircle is given by the formula P = πd + d, where P is the perimeter, d is the diameter, and π is approximately 3.14.
Given that the perimeter P is 17.476 cm, we can set up the equation:
17.476 = πd + d
To solve for d, we first combine like terms:
17.476 = d(π + 1)
