How do you fing the circumference if you have the radius?
you have to use the formula : C= 2* radius* Pie symbol. * IS MULTIPLYING. Pie always equals to 3.14, so suppose the radius is 5. You would multiply 5*2*3.14. Your answer would be 31.4.The reason you have to multiply the radius by 2 is because you have to make the radius turn into the diameter which is double the radius to make the equation simpler. Always remember to use pie as 3.14.
What is the area of a circle if the radius is 20 m in terms of pi?
If i remember the 'ol math class circle area is equal to radius squared times pi so 20x20x3.14 = 1256 meters squared
What is the area of a circle with the radius of 15 milliter to the nearest 10th?
If I remember correctly Area of a circle is... PIE multiplied by the RADIUS squared. If this is so.... 15 is the radius and... The sum of 15 x 15 should be multiplied by pie (3.1415 or what ever it is). Use a calculator to get to the nearest tenth.
Is A radius is an angle that connects to any point on the circle to the center of that circle?
The question is: Is A radius is an angle that connects to any point on the circle to the center of that circle? A Radius is a straight line coming from any point of the circle to the center of the circle. And remember that the Diameter is a straight line coming from any point of the circle and going straight through the center to the other side of the circle. The Radius is ALWAYS half of the Diameter; and, the Diameter is ALWAYS twice the Radius.
