Answer: x-y=7
Step-by-step explanation:
Answer: 2/3πx³
Step-by-step explanation:
Let the radius of the cone be represented by x.
Since the height of the cone is twice the radius of its base, the height will be: = 2x
Volume of a cone = 1/3πr²h
where,
r = x
h = 2x
Volume of a cone = 1/3πr²h
= 1/3 × π × x² × 2x
= 1/3 × π × x² × 2x
= 1/3 × π × 2x³
= 2/3πx³
Therefore, the correct answer is 2/3πx³.
1) X=159
2) BCD=103
3) DCH=89
im pretty sure
Answer:
A
Step-by-step explanation:
Find AB using the Law of Sine:

Thus:

Multiply both sides by sin(40)


AB = 31.0056916 ≈ 31.0 cm (nearest tenth)
