Answer:
Explanation:
The area of a triangle with base b and height h is A = 1/2 * b * h. For example, if b = 5 and h = 10, then the area of the triangle is A = 1/2 * 5 * 10 = 25 square units.
The circumference of a circle with radius r is C = 2 * pi * r. For example, if r = 3, then the circumference of the circle is C = 2 * pi * 3 = 6 * pi = 18.84955592153876 units.
The volume of a rectangular prism with length l, width w, and height h is V = l * w * h. For example, if l = 3, w = 4, and h = 5, then the volume of the rectangular prism is V = 3 * 4 * 5 = 60 cubic units.
The surface area of a sphere with radius r is S = 4 * pi * r^2. For example, if r = 2, then the surface area of the sphere is S = 4 * pi * 2^2 = 4 * pi * 4 = 50.26548245743669 square units.
