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.
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
Mean = sum(X)/n = 15cm/5 = 3cm
There are about 2.54cm = 1 inch and so divide each measurement by 2.54 to convert them into inches.

That would have to be cubic cm. 216 of them.
Perimeter = 2 x L + W so L + W = 9, this would be 6 x 3 to give area of 18
