The area of a circle is pi r2
If r = 3, that makes the area roughly 28.27
r=9yd
r = -0.925 is stronger.
Surface Area=4/3*pi*r2 Where r=radius Volume= 4*pi*r3 Where r=radius There are NO equations for the area or the lateral area

Area = pi*0.52 = 0.785 square units to 3 d.p.
Area = pi*742 = 17203.361 square feet to 3 dp
if r=5z and 15z =3 then r=10y
I
r = 5z 15z = 3y (divide by 3 to both sides) 5z = y r = y
r=9yd
3 equals rings in a circus
It depends on what "a r equals 8" means.
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
Surface Area = pi*r*s + pi*r*r = 3.14*2*9 + 3.14*2*2
If the shape is a perfect sphere, then the ratio of surface area to volume will always be: 4πr2 / 4/3πr3 = 3/r If the volume = 500m3, then we can say: 500m3 = 4/3πr3 375m3 = r3 r = 5∛3 m So the ratio of surface area to volume on that sphere would be 3 / (5∛3 m), or: 3∛3/5m
