Answer: $150
Step-by-step explanation:
If Bilbo bought the ring for 70% of the original price, this means that he saved:
= 100% - 70%
= 30%
$45 is therefore 30% of the original price.
Assuming the original price is x:
30% * x = 45
x = 45/30%
x = $150

Answer:
7.9 in³
Step-by-step explanation:
Given:
Height of cone = 4 in.
Diameter of cone = 2¾ in
Radius (r) = ½ of 2¾ = 1.375 in
Required:
Volume of the cup
Solution:
Volume of the cup = volume of a cone
Volume of a cone = ⅓πr²h
Plug in the values of π, r and h into the formula.
Volume = ⅓*3.14*1.375²*4 = 7.9 in³ (approximated to the nearest tenth)
