the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the <u>radius will be 3</u>
slant height is

h is 4.7 and r is 3

<u>slant height is 5.58427</u>
lateral surface area


<u>lateral surface area is 52.63053</u>
total surface area



<u>total surface area is 80.90486</u>
Step-by-step explanation:
x - 1 = - 3x - 14
Bringing like terms on one side
x + 3x = -14 + 1
4x = - 13
x = - 13/4
Answer: 2 miles
Step-by-step explanation:
Afternoon-x; morning- 1.5x; Evening: 1/2x
Make a equation: 1.5x+x+1/2=6
2.5x+1/2x=6
5/2x+1/2x=6
6x=12
x=2
Answer:
Option D
Step-by-step explanation:
In the first three options we can evaluate the values of x with the help of Sine Rule for all the triangles
The Rule says

Where a , b and c are the sides opposite to the angles A, B and C of any ΔABC.
Hence , in order to determine unknown values of sides or angles , we need any 3 values from all 3 sides and 3 angles in a triangle. First Three options give us three values but the last option gives only 2.
Example
in first option we can apply Sine Rule as





A) 60mph
B) 209.7 miles
C) 2 hours and 45 minutes
