To find the height of the net diagram of the right circular cylinder, we need to calculate the total surface area.
The surface area of a right circular cylinder can be calculated using the formula:
Surface Area = 2πr² + 2πrh
Where r is the radius of the base of the cylinder and h is the height.
In this case, we have two circles with radius 3 feet, so the total surface area is:
395.64 feet² = 2(3.14)(3)² + 2(3.14)(3)h
395.64 = 18.84 + 18.84h
Subtract 18.84 from both sides:
376.8 = 18.84h
Divide by 18.84 to solve for h:
h = 20 feet
Therefore, the height of the net diagram of the right circular cylinder is 20 feet.
Question
Use the image to answer the question.
An illustration shows a rectangle of unknown height with a circle of radius 3 feet attached to its top left and a circle of radius 3 feet attached to its bottom right. THANK YOU BOT FOR THE AWNSERS
If the surface area of the net diagram of the right circular cylinder is 395.64 feet2 , find the height of the net diagram. Use 3.14 for π .
