If the triangle has 45, 45, and 90 degrees, then its sides are x, x, and ________. (x*sqrt2)
What will be c if the other two sides of the triangle are a=3 and b=4? 5
What will be b if the other two sides of the triangle are a=5 and c=13? 12
What's the volume of a rectangular solid? Length*Width*Height
Surface area of a rectangular solid = (2*Length*Width) + (2*Length*Height) + (2*Height*Width)
Volume of a cube = (e^3)
Surface area of a cube = 6*(e^2)
Volume of a cylinder = (Pi)*(radius^2)*(Height)
Lateral surface area of a cylinder = 2*(Pi)*(radius)*(Height) [Circumference*Height]
Total surface area of a cylinder = [2*(Pi)*(radius^2)] + [2*(Pi)*(radius)*(height)](Area of circular ends + Lateral surface area)
The sum of the lengths of any two sides of a triangle must be ________ than the length of the third side. Greater
