Mean = sum(X)/n = 15cm/5 = 3cm
Let x be the length of one of the congruent sides, then the three sides are x, x, 3x. Perimeter = x + x + 3x = 5x = 75cm => x = 15cm Thus the three sides are 15cm, 15cm, 45cm.
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
Volume = 2cm x 2 cm x 2 cm = 8 cm^(3).
The volume of a cube is calculated by multiplying the length, width, and height of the cube. In this case, all sides of the cube are 2cm. Therefore, the volume of the cube would be 2cm x 2cm x 2cm = 8 cubic centimeters.
