Formula: (2*pi*radius2)+(2*pi*radius*height) = area
So: (2*3.14*r2)+(2*3.14*r*2.7) = 354.156832
Dividing all terms by 2*3.14: r2+2.7r = 56.3944
As a quadratic equation: r2+2.7r-56.3944 = 0
Solving the equation: r has a positive value of 6.28
Therefore: radius in question = 6.28 cm
Check: (2*3.14*6.282)+(2*3.14*6.28*2.7) = 354.156832 square cm
Entire surface area of a cylinder = (2*pi*radius2)+(diameter*pi*height)
Entire surface area = (2piradius2)+(pidiameterheight) in square units
Surface Area = 2(pi r 2) + (2 pi r)* h
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Entire surface area = (2pi72)+(14pi10) = 747.699 square units to 3 decimal places
Entire surface area = (2*pi*radius2)+(pi*diameter*height)
Entire surface area of a cylinder = (2*pi*radius2)+(diameter*pi*height)
One of the most accurate methods of showing the entire surface of the Earth is by using a globe, as it represents the planet's spherical shape and provides a three-dimensional view. Another method is by utilizing maps that utilize projections such as the Winkel Tripel projection, which seeks to minimize distortion across the globe's surface. Ultimately, the choice of method depends on the specific purpose and context in which the Earth's surface needs to be depicted.

Change the mixed numbers into improper fractions or decimals and use the formula for the cylinder's entire surface area of: (2*pi*radius2)+(pi*diameter*height)
Entire surface area = (2pi32)+(pi65) = 150.796 square inches to 3 decimal places
