Answer:
3 8/33
Step-by-step explanation:
Answer:
6.9 foot.
Step-by-step explanation:
Given: Length of lamp post= 12-foot.
The angle of elevation of the sun is 60°.
∴ The length of Lamp post, which is opposite is 12-foot.
Now, finding the length of shadow cast by foot lamp.
Length of shadow is adjacent.
∴ We know the formula for
= 
Next, putting the value in the formula.
⇒ 
Cross multiplying both side and using the value of Tan 60°
∴ Adjacent=
≅ 6.9 (nearest tenth value)
6.9 is the length of shadow cast by a 12-foot lamp post.
If by base of 10, you mean that the diameter of the base is 10, then the radius of the base is 5.
volume = pi * r^2 * h
volume = pi * 5^2 * 10
volume = 250pi, or approximately 785
46+19+54= 119, so the answer is 119
