Well, darling, 4 times x squared is simply 4x^2. It's as easy as pie, no need to complicate things. Just plug in your x value and do the math, honey.
142*3.14*pi = 1933.46 (approx)
if you mean PI squared + PI squared / by 2 then that is.... 4.9298 solved on paper ... BUT if you mean what you said, the answer is YUMMY!
x2 + 8x2 = 9x2
Well take (2 squared by 3) that would 2 times 2 which is 4, times 2 which equals 8 so (2 squared by 3) eqauls 8

pie times radius squared
well the formula to find the area of a circle is Area=pie x radius squared so if i say calculate the area of a circle with the following measurements giving your answer in terms of pie. Radius=8cm Area=pie x radius squared Area=pie x 8 squared Area= 64 pie cm squared If you do this calculation on your calculator ( pie x 8 squared) you should get the same answer. I hope this helped. If you need anything else veryfying then please ask. :)
for the surface area:4 times pie times radius squared for volume:4/3 times pie times radius cubed
This is not going to come out as any neat number. The answer is (11/2) squared times pi divided by 8.
576cm squared.
area of what? circle is pie times the radius squared, rectangle is base times height, and a square is the side squared
Well, 8 squared means 8 times 8. so yea, 8 times 8 equals 64
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
142*3.14*pi = 1933.46 (approx)
The average diameter of a moose, as measured from the shoulder, is around 30-40 inches.
