Answer:
The length of shadow is 69 foot.
Step-by-step explanation:
We are given a shadow of lighthouse.
Length of top of lighthouse to end of shadow is 90 ft.
Angle make at top of lighthouse is 50°
Distance from foot of lighthouse to end of shadow is x ft.
we need to find the length of shadow i,e x ft
Using trigonometry ration:




Hence, The length of shadow is 69 foot.
Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V =
× 3.14 × 9.3³
=
× 3.14 × 804.357
= 
≈ 3367.6 cm³ ( to the nearest tenth )
-10 is the correct answer
Answer:
h = 2 cm
402 over 3.14 x (8) to the power of two. SImplifies to about the answer of 2
