2 times the radius equals what?
Radius time 2 equals the diameter.
What is the length of the radius if the circumference equals 18x3.14 for pie?
9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
Formula for surface area of a cylinder?
2 times pi times the radius squared plus 2 times pi times the radius times the height equals surface area of a cylinder :]
Which equation could be used to find the circumference of a ball with a radius of 5 inches?
The circumference of a circle equals 2 times pi times the radius, in this case, about 31.42 inches.
What is the radius of a circle with diameter of 8inches?
The radius of a circle with diameter or 8 inches is 4 inches. The diameter equals 2 times the radius or d=2*r. --> 8 in = 2*r so, r = 4 in
2 times the radius equals what?
Radius time 2 equals the diameter.
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
Is the radius and diameter related?
Yes ... The Radius Times 2 Equals The Diameter

What is the formula to calculate the area of a circle?
*=multiplication symbol /=division symbol r*(r*ㅠ)=r2 ......... radius*(radius*pi)=radius2 ........... radius times the radius times pi equals radius squared HINT HINT HINT an easier way to put this is .......... d*ㅠ/2=n ............. diameter*ㅠ/2=answer .......... diameter times pi divided by two equals the answer
What is the radius of x2 plus y2 equals 9?
X2 or 2 times x?
Which equation could be used to find the circumference of a ball with a radius of 5 inches?
The circumference of a circle equals 2 times pi times the radius, in this case, about 31.42 inches.

Is the area of a circle is twice the radius?
Area equals pi times the radius squared.
What is area of a circle if circumference equals pi divided by 2?
Area of a circle is: pi times radius squared
If the radius equals 2cm what is the circumference?
C = 2 * (pi) * (radius) So plug in 2 for radius C = 2 * (pi) * (2) C= 4(pi) If you need to approximate multiply 4 times 3.14. If you do not need to approximate then your answer is 4(pi)
