What expression could be used to find the volume of a cylinder with the height of 5cm and a 3cm?
Volume of a cylinder = pi*radius2*height
Additional mathematic project?
There are plenty of mathematic projects available to make. You could show the effects of addition by creating an ant farm and showing what happens when you have two populations that combine.
What mathematic did Fibonacci do?
Fibonacci study trigonometry it is dealing with trangles
Why are multiplication division addition and subtraction used in evaluating expressions?
If they are present in the expression you need to use them to evaluate the expression, if they are not, you don't. You would not use any of them - at least not explicitly - to evaluate sqrt[ln(pi)], for example.
What is the exact value of the expression cos 7pi over 12 cos pi over 6 -sin 7pi over 12 sin pi over 6?
cos(a)cos(b)-sin(a)sin(b)=cos(a+b) a=7pi/12 and b=pi/6 a+b = 7pi/12 + pi/6 = 7pi/12 + 2pi/12 = 9pi/12 We want to find cos(9pi/12) cos(9pi/12) = cos(3pi/4) cos(3pi/4)= cos(pi-pi/4) cos(pi)cos(pi/4)-sin(pi)sin(pi/4) cos(pi)=-1 sin(pi)=0 cos(pi/4) = √2/2 sin(pi/4) =√2/2 cos(pi)cos(pi/4)-sin(pi)sin(pi/4) = - cos(pi/4) = -√2/2
What is the billionth digit of pi?
The billionth digit of pi is 9. http://www.geocities.com/ultrastupidneal/Knowledge-Mathematic-Fact.html
The date is 7-22 if you divide 22 by 7 you get an approximation of what tasty-sounding mathematic constant?
Yummy Pi!
What is a good expression to find out the diameter of a circle with a circumference of 36 centimeters?
circumference=pi*diameter so diameter=circumference/pi 36/pi=11.4591559
What awards did he get on his books?
None On Next Expression: a = pi(r squared)
What is the approximate value for pi as a rational expression?
Pi is about 3.14159265. You can round that to as many or as few significant digits are are appropriate for a particular application.
What is the radical expression of 180?
There are pi radians in a half of a circle, or in 180 degrees.
What expression represents the volume of a cylinder whose height is equivalent to the length of the radius?
The volume of a cylinder is PI * R2 * H If H is the same as R, then it is PI * R3 (Or PI * H3)
What is the symbolic expression for the circumference of a circle?
The circumference is 2 x pi x radius.
Does simplyify mean to subtract?
Not necessarily. To simplify means to replace a mathematic expression with something equivalent, but simpler. This may involve subtracting in some cases, but simplifying may involve other operations as well.
How do you figure the length of a circle?
The circle's length (or circumference) is determined with the expression C=D(pi).
Which expression gives the surface area of a sphere with a radius r?
Area = 4*pi*r^2
What is 3.24 in mathematic?
It is a rational number.
