Phythaforas' Theorem: Finding the Circumference of a Circle

The video tutorial explains how to solve a geometry problem involving a circle with points M, N, and P. It guides through calculating the diameter using Pythagoras theorem and then finding the circumference using the formula C = πD. The tutorial highlights the importance of correct substitution, square rooting, and rounding to three significant figures. It also discusses the marks allocation for each step and emphasizes the need to remember key formulas for exams.

What is the value of C^2 when using the lengths 3.5 cm and 9.7 cm?

Describe the process of rounding the circumference to three significant figures.

What are the two essential formulas needed to solve the problems in this quiz?
