The equation for a cone is
V=(1/3)hpir^2
if pi=aprox 3.14 for this quesiton
and r=6 and h=13
V=(1/3)(13)(3.14)(6^2)
V=(1/3)(13)(3.14)(36)
V=(13)(3.14)(12)
V=(3.14)(156)
V=489.84 cubic units
Answer/Step-by-step explanation:
∆ABC is similar to ∆CDE. Therefore, the ratio of their corresponding sides are proportional.
This,


Solve for x






Use the value of x to find AC and DC


I don’t know the answer sorry
Answer:
<h3>Option 2 </h3>
angle 2 = 7x + 1 ( vertically opposite angles)
7x + 1 + 18x + 4 = 180° ( forming linear pair).
7x + 18x + 4 +1 = 180°
25x + 5 = 180°
25x = 180 - 5
25x = 175
x = 7°
angle 2 = 7(7)+ 1
= 50°
Answer:
4.71
Step-by-step explanation:
Arc length = 2*pi*r-(pi*r)/2
Arc length = 3*2*(3.14)/4 = 4.71
