Answer:
C.
Step-by-step explanation:
First finding height using Pythagoras theorem
(H)²=(B)²+(P)²
8.2²=5.4²+P²
P² = 67.24 - 29.16
P² = 38.08
P = 6.2
Now
Volume of cone = (1/3)πr²h
= (1/3)(3.14)(5.4)²(6.2)
= (1/3)(567.9)
= 189.2 cm³
Answer:
x + 13 / x + 17
Step-by-step explanation:
x - 4 / x
x + 13 / x + 17
63/12 = 4.2
4.2 x 12 = 50.4
x = 50.4
