A circle with a radius of 10m has an area of 314.16 m2
The area of a circle with a radius of 2m is: 12.566 m2
A rectangle measuring 3.2m x 10m has an area of 32m.

Since you didn't state If the 2m was a diameter or radius, it will have to be calculated as If it were both: Diameter: Pi x D = Area of Circle 3.14 x 2m = 6.28 m² Radius: Pi x R² = Area of Circle 3.14 x 2m² = 3.14 x 4 = 12.56 m²
surface area = 2 x pi x r x h = 2x22/7x2x10 = 880/7 = 125.7 (approx.)
The surface area of a cylinder with a radius 2m and 9m height is 138.23m2
30 percent of 2m = 0.6m30% of 2m= 30% * 2m= 30%/100% * 2m= 6/10m or 0.6m
10m - 7
The surface area depends on the shape, not just the length of sides.
The 3 measurements make a cuboid 3D shape: 10m long x 6m wide x 2m depth. 1 top and 1 bottom = 10 x 6 x 2 = 120m2 2 sides = 10m x 2m x 2 = 40m2 2 ends = 6m x 2m x 2m = 24m2 Therefore total area is: 120 + 40 + 24 = 184m3
The answer is -2m
Determine the area of one face (2m x 2m = 42m). Multiply by the number of faces on a cube - 6. So, 6 x 42m = 242m total surface area.
Determine the area of one face (2m x 2m = 42m). Multiply by the number of faces on a cube - 6. So, 6 x 42m = 242m total surface area.
12m + 9n - 4 - 10m + 6n = 2m + 15n - 4
Total surface area = 2*pi*r*(r + h) = 69.1 sq metres, approx.
It is: 6*2*2 = 24 square m
