Volume of a cone = 1/3 π r² h
235.5 = 1/3 (3.14) r² (9)
(3.14) r² (9) = 706.5
r² = 25
r = 5
Answer: Radius = 5 cm
Answer:
8
Step-by-step explanation:
Evaluate 3x^2+x-2 when x=-2
Just plug in x = - 2 into the expression
= 3(-2)^2 + (-2) -2
= 3(4) -2 - 2
= 12 - 4
= 8
Exponential form:12^3
Standard form:1728
Expanded form:12x12x12
