1/2 and 4/8! Both are equivalent!
Solution:
<u>We know that:</u>
- Diameter = 22 meters
- Radius = Diameter/2
- Area of circle = πr²
<u>Finding the radius:</u>
- Radius = Diameter/2
- => Radius = 22/2
- => Radius = 11 meters
<u>Finding the area of the circle:</u>
- Area of circle = πr²
- => Area of circle = (3.14)(11²)
- => Area of circle = 3.14 x 121
- => Area of circle = 379.94 m²
Answer:46
Step-by-step explanation:
You know the definitions of the trig functions tell you
.. cos(78°) = (5 ft)/?
.. ? = (5 ft)/cos(78°) ≈ 24.0 ft
