Surface Area of a Cylinder 81 foot by 10 inches Calculator
Surface Area of Cylinder Base Radius 81 foot by height 10 inches is 20813.4899915 foot2 or 51122.34 inches2
The Surface Area of a Cylinder is equal to the sum of the areas of the bases each having an area of π ⋅ r2, plus the area of the side. The area of the side is equal to the area of a rectangle with length 2 π r (the circumference of the base) times the height. Surface Area of Cylinder Base Radius 81 foot by height 10 inches is 20813.4899915 foot2 or 51122.34 inches2.

Steps:
Given that Base radius(r) = 81 ft and height(h) =10.0 in
The Surface Area of Cylinder = 2π .(Radius)2 + 2π .(Radius) . (Height)
Substitute the values of the radius r = 81 ft and height h = 10.0 in into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of Width 10 in = 0.8333333 ft
10 Inches is 0.8333333 feet
To convert Inches to Feet
we know that, 1 Inches = 0.0833333 Feet or
1 Foot = 1/12 foot
To convert Inches to Feet, divide the inche value by 12.
Result in Foot: 10 × in/12 × ft/in
Cancel The Comman factor of in
Result in Feet: $10\above 1pt12$
Divide the 10 by 12
Result in Feet: 0.8333333 feet
∴ 10 Inches = 0.8333333 feet

Unit Conversion of Length 81 ft = 972.0 in
81 Foot is 972.0 inches
To convert Foot to Inches
we know that, 1 Foot = 12 inches
To convert Foot to inches, multiply the foot value by 12.
Result in Foot: 81 ft × 12 × in/ft
Cancel The Comman factor of ft
Result in Inches: (81 x 12 in)
Multiply 81 into 12
Result in Inches: 972.0 inches
∴ 81 Foot = 972.0 inches
