5*4 = 20 square inches
twenty inches
Surface area: (2*0.5*3*4)+(3*9)+(4*9)+(5*9) = 120 square inches
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 in, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 square inches
The surface area of a cylinder is given by the formula 2πr(r+h), where r is the radius and h is the height. In this case, the radius is half the diameter, so it is 4 inches. Thus, the surface area of this cylinder is 2π(4)(4+5) = 2π(4)(9) = 2π(36) ≈ 226.195 square inches.

The area of a right angle that has a base of 3 inches height of 4 inches and a 5 inch hypotenuse is: 6 square inches.
A "3-4-5" right angled triangle has an area of 6 sq inches. (3x4)/2
Surface area: (2*0.5*3*4)+(3*9)+(4*9)+(5*9) = 120 square inches

You have given 3 dimensions and not the shape. For area you generally need two dimensions, like for a rectangle. The area of this is Length by width.
The area of a square with sides that are 4 inches is 16 inches. You multiply 4 and 4 and get the area.
To find the area of a rectangle, multiply the length times the width.
The area is 64 units. Checked on a calculator .^^
