00:09 Which shape has a bigger perimeter?
00:12 Let's find the circle's perimeter using its diameter.
00:16 First, we'll use the perimeter formula for a circle.
00:27 Next, plug the circle's diameter into the formula and calculate.
00:32 And there you have it, this is the circle's perimeter.
00:35 Now, let's look at the second circle's diameter.
00:40 We'll use the same method to find this perimeter too.
00:46 Again, enter the diameter into the formula and solve.
00:53 Here you go, this is the perimeter for the second circle.
01:01 That's how you find which circle has a larger perimeter.
