Answer:
Your answer is 34 1/2, have a great day and happy holidays!
Step-by-step explanation:
Answer. C (yes; by SAS)
We know that opposite angles formed by the intersection of two lines are congruent:
Therefore, Angle HMG ≅ Angle JMK
Line HM : Line MK
= 8:12
= 2:3
Line GM : Line MJ
= 6:9
= 2:3
Therefore,
HM ≅ MK
GM ≅ MJ
Therefore, we have one pair of congruent angles, and a pair of congruent sides.
⇒ The two triangles are congruent by SAS theorem.
12/7 = 20/x
12x = 140
x = 140/12 = 35/3 = 11.67
so radius of the large cone = 11.67 ft
Volume = 1/3 πr^2h
= 1/3(3.14)(11.67)^2(20)
= 2850.88
Answer is B. 2850.70 ft^3
