What is the area of the triangle 10cm ,8cm and 6cm
A = 2480cm
24CM
48
Using 3.14 as Pi the area of circle is: 200.96
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
Find the area of 5cm 12cm 8cm
That would depend on its radius which has not been given but the area of a circle is pi times radius squared
Total surface area is 905 cm2
125.7 cm2
This cone has a lateral surface area of approximately 226.73cm2
A square of perimeter 32cm has 4 sides of length 8cm. Area = Side1*Side2 Area = 8cm*8cm Area=64cm2
A cylinder whose radius is 2cm and height is 8cm has a total surface area of approximately 125.66cm2 {ADDED} To explain that further, the formula is pi*r^2 X h where r is the radius and h the height.
A cube has be definition has slides all of the same length, which in turn means all six faces are squares, in this case 8cm along each side. Once side would have an area of 8cm x 8cm which is 64 cm squared but you have six of them 6 x 64 cm squared is 384 cm squared
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
32 cm² = 8cm²/2
the area of a 2D shape with dimensions 8cm and 12cm is 96cm2, but if you're talking about surface area of a 3D shape then you need the other dimension.
