x= 1.68596491
So just round that number and you have your answer.
Step-by-step explanation:
A is the answer to the question
use soh cah toa!
Step-by-step explanation:
soh= sin opposite/hypotenuse
sin (65°) 5/x
* x *x
x* (sin 65°)= 5
x (0.906308) =5
÷0.906308 = ÷0.906308
x≈ 5.51689
x≈ 5.5
The answer would be 18.2 gallons because they used up 5.8 gallons, they still have 12.4 gallons that they did not use and in order to get the original amount of gas they had before the trip, you would add up 12.4 and 5.8 to get the Original amount. Hope this helps.
Answer:
<u>d = 2r or d = C/π</u>
Diameter is equal to two times the radius or Circumference/π
<u>C = 2πr</u>
Circumference is equal to two times π multiplied the radius
<u>A = π * r²</u>
The area of the circle equals to π multiplied by the radius squared
Step-by-step explanation:
Let's find the formulas for d, C and A
d = diameter
C = Circumference
A = Area
r = radius
π ≅ 3.1416
d = 2r or d = C/π
Diameter is equal to two times the radius or Circumference/π
C = 2πr
Circumference is equal to two times π multiplied the radius
A = π * r²
The area of the circle equals to π multiplied by the radius squared
