A sphere with a diameter of 16 meters has the same surface area as the total surface area of a right cylinder with the base diameter equal to the sphere diameter how high is the cylinder?
Surface Area of Sphere = 4*Pi*r2 Surface Area of Cylinder = 2*Pi*r2+2*Pi*r*h If we set them as equal: 4*Pi*r2 = 2*Pi*r2+2*Pi*r*h ' Factor out 2*Pi*r 4*Pi*r2 = 2*Pi*r*(r+h) ' Divide both sides by 2*Pi*r 2*r=r+h ' Subtract r from both sides r=h Diameter = 2*r so h=d/2 In this case, d=16m h=8m
How many gallons of water in one half inch copper pipe 1 foot long?
you would measure this same way as a cylinder Radius=r pi = 3.14159 (approx.) Area=A Height=h Volume=v First calculate the area of the circle: A=pi*r*r Then multiply by the height to attain volume: v = A*h = pi*r*r*h

What is the surface area of a cylinder with the radius 2.5 yards and height 6 yards?
The total surface area is 2*pi*r*(r + h) where r is the radius and h the height.= 2*pi*2.5*8.5 = 133.52 sq yards.The total surface area is 2*pi*r*(r + h) where r is the radius and h the height.= 2*pi*2.5*8.5 = 133.52 sq yards.The total surface area is 2*pi*r*(r + h) where r is the radius and h the height.= 2*pi*2.5*8.5 = 133.52 sq yards.The total surface area is 2*pi*r*(r + h) where r is the radius and h the height.= 2*pi*2.5*8.5 = 133.52 sq yards.
What is formula of cone?
V = ⅓•π•r²•h Where: - V: Volume of Cone - π: Constant (Ratio of Circumference to Diameter for any Circle) - r: Radius of Base - h: Vertical Height Tsa = π•r(r+√(r²+h²)) = π•r(r+l) Where: - Tsa: Total Surface Area (i.e. Base inclusive) - π: Constant (Ratio of Circumference to Diameter for any Circle) - r: Radius of Base - h: Vertical Height - l: Slant Height = √(r²+h²) (Using Pythagorean Theorem) SA = π•r(√(r²+h²)) = π•r•l Where: - SA: Lateral Surface Area - π: Constant (Ratio of Circumference to Diameter for any Circle) - r: Radius of Base - h: Vertical Height - l: Slant Height = √(r²+h²) (Using Pythagorean Theorem)
