What happens to the radius of a cone if a cone of say radius 8 cm is cut in half?
just do it regularly then divide the volume by four when you get the volume answer ============================================================= The original cone is say, 3 cm high and has a radius of 8 cm. the formula is pi times the radius squared times the hight, so pi*64*3=192pi. the second formula is 3*4 squared times pi, so 48pi, which is one fourth of 192 pi.
What is the volume of a cylinder with a radius of 9 cm and a height of 8 cm?
648pi. (pi = 3.14159...)Area of a circle = (pi) x (radius squared)= (pi)(9 squared) = (pi)81.Area of a cylinder = area of circle x height.= (pi)81 x 8= 648(pi)
What is PI to the negative alpha squared?
-8. alpha x 17.81
How do you find diameter of a circle with the area of 8in pi cm squared?
You use the formula A=(pi)r^2 solve for r which will give you the square root of A/pi. In your case the area has pi already in it so it is just 2 times the square root of 8.
What is the sector area of a circle that has a radius of 8 cm and has a subtended angle of 50 degrees at the circle's centre?
Area of the sector: 50/360 times pi times 8 squared = 27.925 square cm to 3 dp
How many square inches in 16 inch round pan?
The area of a circle is pi x radius2. You know the radius already since it's diameter/2 which is 8 inches. Your answer then is pi times 8 inches squared which is 64 times pi inches squared. pi is about 3.1415 so multiply that by 64 if you need to resolve the pi.
What is the area of a circle with a radius of 8?
Area = Pi times the Radius squared -- pi x r^2Note: pi = 3.1415926535897932384626433832795Area = 3.14159 x 8^2Area = 201.06176 (units)^2
What does the square root of X times three squared times the sum of pi equal?
It looks like this:√x (2)3 · Σ πIt equals:i 8 sum Pi.
What is the area of the area of a 16 diameter in tems of pi?
area = pi*8 squared

72cm squared times 8?
576cm squared.
What is the difference between the area of a circle with a diameter of 8 units and the area of a circle with a radius of 2 units?
The diameter is two times the radius. a diameter of 8 units is 16 units of radius. Since area is proportional to radius squared ( pi x radius squared) then the area ratio of the bigger circl is (16/2) squared or 8 x 8 = 64 times greater.
What does 8 squared equal?
Well, 8 squared means 8 times 8. so yea, 8 times 8 equals 64

How many cubic inches is a 350 bored 40 over?
3.14159*2.02*2.02*3.48*8=357 In words: pi are squared times stroke times number of cylinders.
