calculate the circumference.\nformula:\nc = 2πr\nuse 3.14 for π.\nc = ? cm\nround to the nearest tenth.
Answer
Explanation:
Step1: Substitute the values into the formula
Given ( r = 10) cm and (\pi=3.14), the formula for the circumference of a circle is (C = 2\pi r). Substituting the values, we get (C=2\times3.14\times10).
Step2: Calculate the result
First, calculate (2\times10 = 20). Then, multiply by (3.14): (20\times3.14=62.8).
Answer:
(62.8)
