Question

Find the circumference of a circle with radius, r
= 1.6m.
Give your answer rounded to 1 DP.

Answer 1

Answer:

Answer = 10.1

Step-by-step explanation:

Circumference of circle = 2πr

r = 1.6m π = 3.14 or 22/7

2 x 3.14 x 1.6 = 10.048

rounded to one decimal place = 10.1

Answer 2

find circumference of circle , if the radius = 1.6m

we all know the formula of circle to find it's circumference that is = 2πr

where the value of π = 22/7 or 3.14

now , put the digits in formula

= 2 × 3.14 × 1.6m

= 10.048m
