3*pi = 9.424777961 to nine decimal places.
When you multiply 12.8 times pi the exact answer is12.8 Pi, but you can round off the answer to40.192because pi is about equal to 3.14.
pi times radius or diameter equals are of a cirlce
Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4
The answer is Pi times radius squared. Although you can't know anymore since you don't give what the radius is. Although, Pi can be simply referred to as 3.14
No. Circumfrence=2 times pi times radius. And since the daimeter = 2 times radius, circumference is diameter times pi.
(pi) R2 x 34 = 81 pi R2
3.385137501 this is true, I did it on my calculator!
circumference of a circle = diameter*pi or 2*pi*radius
(pi)xr2xh÷3 (area of base x height) (pi) times radius squared times height divided by three
Yes because circumference = diameter*pi and the value of pi is just over 3
the same as pi squared, which is 9.86960440109
It looks like this:√x (2)3 · Σ πIt equals:i 8 sum Pi.
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
pi^2
area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)
