Answer:
43
Step-by-step explanation:
multiply 4 x c(12)=48
then just plug it in and solve
82-48=34
34+9=43
The area of the sector 2π/3 radians with diameter 10 feet 75π feet²
The arc period of a circle can be calculated with the radius and relevant perspective using the arc period method.
Diameter = 10 feet
radius = 5 feet
angle = 2π/3 radians
⇒angle= arc/radius
⇒ 2π/3 radians° =arc/10
⇒ arc =2π/3 radians *10
⇒arc=2π/3 radians*10
⇒arc = 20/π43 feet
Area of a circle = π*r²
= π*5² = π25
∵ area of complete circle is π25
∴ area of 2π/3 radians = π25/2π *2π/3 radians
= 75π answer

The measure of angle FDE must be 90 degree, if D is a point on the circle. If D is not a point on the circle, we are unable to determine the measure of angle FDE.
When you have angle with the vertex on a circle and the sides go through the ends of the diameter, the angle is always a right angle.
