How to calculate the area of a circle

טקסט Storyboard

  • well, I know just that. let's got take a look at this table.
  • Well, There's a table I saw that I liked the size of, but it's a circle. I don't know how to calculate the size of a circle!
  • you need to know the area of the table before you build one like it.
  • Table
  • Don't forget the tape measure - and a calculator
  • your car is too small mom
  • Today's Special:Cherry Chocolate
  • got it. Here.
  • Myra wants to build a table for her living room. She saw one in an Ice cream parlor that she liked the size of, but she doesn't know how to find out how big it is.
  • Today's Special:Cherry Chocolate
  • what's radius mean?
  • Oh... OK. Well, I measured the length of the whole table and it is 24 in.
  • She and her mom are going to find out how big it is.
  • Today's Special:Cherry Chocolate
  • so what now?
  • Ok... First, you need to find the middle of the table. Ok, now you need to measure the radius.
  • Today's Special:Cherry Chocolate
  • So if I multiply 144 and 3.14, I get 452.16.That means the area of the table is 452.16 inches.
  • Radius is how long it is from the middle of the circle to the edge of the circle.So... divide that by 2 and you get... 12!
  • Now, you need to multiply the radius(12) by Pi(3.14) But... there's a twist. first, you need to square the radius. So, 12 squared is 144. now multiply the numbers
  • Precisley! Good Work. Let's go build your table.
