(pi times radius squared) plus (pi times radius times slant).
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
[2 pi times (the radius squared)] plus [(2 pi times the radius) times the height] the parentheses are according to the order of operations
the volume of a cylinder is (pi)r squared times the height, same as a circle but plus the height so the answer here would be ((pi) x 1) squared x 5. or 5 pi squared
Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)

Pi plus 86 equals 89.14
Yes
(pi + pi + pi) = 3 pi = roughly 9.4248 (rounded) Well, if you use the common shortened version of pi which is 3.14 and add that 3 times, you get 9.42.

the same as pi squared, which is 9.86960440109
It is irrational, just like pi
hi
19.7392088 is also = to pi for instince infinaty=pi = never tnding so the formlea infinity=pi.
3 + pi =3πor6.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823066470938446095505822317253594081284811174502841027019385211055596446229489549303819644288109756659334461284756482337867831652712019091456485669234603....

If we have 2 x 4 + pi, we'll have 8 + pi, or about 11.1416 for an answer.
