because if you estimate it will elp you understand what the problem you are doing.For in example.what is 20 tims 84 so you esitmate near the tens place. my esitmate was 1,600 because 20times 80= 1,600.the real answer is 1,680
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The formula for finding the area of a circle is : pi(r) squared. So, that answer would be 13.69cm multiplied by pi, which is nearest to 3.14.
The same as finding the area of a circle which is: pi*radius2
2[4(radius)/3(pi)]
Acknowledged. Let us know when you're done.
Yes.
yes
i really don't know this i am the one who asked it and none of these work for me
Mr. Kevin thinks that estimation can help students get real sense of conversion between fraction and percentage.
It's important to estimate before finding the real answer for any numerical problem in arithmetic or any other kind of math, so that when you think you have the real answer, you can immediately recognize whether it's total baloney or has a chance of being correct.
The estimate of a circle with a circumference of 288 is a circle with a diameter of 91.67
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Area of a circle = pi*radius2
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone
