whats a TT ?if you are entering in terms of pi, just type p after your answer and it'll automatically convert thanks to khan academy :)what is the value of piPi is an infinite number, but 3.14 is usually used in place of pi.How do you solve for the radius of a cylinder when you are not given the diameter but you have the h...Note that the radius is simply half the diameter. The formula for the volume of a cylinder is: V = Π x r^2 x h "Volume equals pi times radius squar...I know this is weird, but now I really want some pieHappens to everyone. ;)I'm confused. I get how you do surface area of a circle and why you have to do it twice, but I don't...To calculate the surface area of the middle part of the cylinder, I like to think of it as a rectangle. The area of a rectangle is length x width....In the end: how can he get 96 pi square cm since he adds 64 pi square cm and 32 pi square cm? Should...No if you think of pi as x, you are adding 64x + 32x to get 96x, not 96x^2.In a question on surface area, it asks me to answer in a multiple of pi. How do I do that?Once you have simplified your expression in terms of pi, go no further. Just say the answer is 24π or whatever it is.Can someone tell me what the difference between area and volume is(note:i'm not talking about surfac...Area is a planar quantity,which means it's the surface, it's 2D and volume is the amount of space occupied by the object, it's 3DHow do you find the surface area for a sphere?The surface area of a sphere with radius r is given by the formula S = 4pi r^2. Have a blessed, wonderful day!
