Math project 2

Zein(2) Well… what about pi?
(1) Let’s begin with the radius. Now, the radius is half the distance of the circle, meaning it’s half the diameter. So, if you have a diameter of 2, the radius is 1.
Zein(2) Thank you, ms! What about the circumference? (4) Yes, ms. Thank you! May we solve word problems?Ms.Ghada: “sure!”
(1) Well, pi is a numerical value approximated to 3.14, but it’s not exactly 3.14; but you can measure it as 3.14.(3) Regarding the formula for the circumference is 2r x pi, or 2 x pi x r. So, if you have the radius, multiply it by two, and if you have the diameter, just put it with pi directly. That’s the trick. Do you understand?
Zein(2) Firstly, we divide the diamter of 7, so it’ll be 3.5. Then, we multiply 3.5 by 3.5, which is 12.25. Then, we multiply 12.25 by pi, or 3.14. The answer would be 38.47 ft. (4) Well, we already have the diameter, so we don’t need to multiply the radius. So, it’ll be 7pi.
(1) Suppose you have a diameter of 7, what is its area?(3) Well done! Now, for the last question, what would be the circumference of the same question?(5) Well done! I’m sure you’re ready for the quiz now. Bye!
