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.
Is circumference radius times pi?
NO!!!! C = 2 pi r C = pi d In words ; Circumference equals two times 'pi' times radius or , circumference equals 'pi' times diameter. NB The diameter is twice the radius. Also A = pi r^(2) In words, Area equals 'pi' times the radius squared. Read learn and comit to memory these two circle equations.
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.
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.
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
What is The diameter if The radius is 4.25 cm?
The diameter of a circle is twice the radius. Therefore, if the radius is 4.25 cm, the diameter can be calculated as (2 \times 4.25) cm, which equals 8.5 cm.
What is the diameter of the radius was 12 millimeters?
The diameter of a circle is twice the length of its radius. If the radius is 12 millimeters, the diameter would be 2 times 12 millimeters, which equals 24 millimeters.
