⇒ s = a+b+c2=5+12+132 a + b + c 2 = 5 + 12 + 13 2 = 15 cm.
Area of the base = √s(s−a)(s−b)(s−c)
= √15×10×3×2 15 × 10 × 3 × 2 cm2 = 30 cm2

Answer:
= 45.791666666666 mm^3
Step-by-step explanation:
Volume of a cone is given by
V = 1/3 pi r^2 h
We know the diameter = 5
The radius is 1/2 the diameter
r = 5/2
The height is 7
Using pi = 3.14
V = 1/3 *(3.14) * (5/2)^2 *7
= 1/3 *(3.14) * 25/4 *7
= 45.791666666666
