Answer:
option A. 21 sec
Step-by-step explanation:
Speed = the distance over the time
Given:
Speed = 2 m/s and distance = 42 m and time = t
So,
2 = 42/t
Solve for t
t = 42/2 = 21 sec.
The answer is option A. 21 sec
*Hint: The formula for the lateral surface area of a right cone is LA= Πrs
All we have to do is plug in and solve.
LA= Π(3)(5)
LA = 15Π
LA = 47.1238898
The lateral surface area is around 48 inches.
I will give you your answer just give me the equation cause you didn’t write it
Answer:
∠ L ≈ 21.6°
Step-by-step explanation:
Using the Sine rule in the triangle
= 
, that is
= 
( cross- multiply )
42 × sinL = 34 × sin27° ( divide both sides by 42 )
sinL = 
, then
∠ L = 
( ) ≈ 21.6° ( to the nearest tenth )
