Answer: 1) 530.66 ft^2

Step-by-step explanation:

You need to find the area of the circles.

They gave you the formula to find them which is

Area = Pi * R^2    //// Pi times Radius squared will give you the area.

For example, the radius of the 1st question is 13ft. We use it with the formula given.

A = 3.14 * 13^2  /// 13 squared is just 13 x 13 = 169

A = 3.14 * 169   /// Now multiply Pi times 169

A = 530.66      /// Thats your answer.

530.66 ft^2

Consider all angles whose reference angle is 45° with terminal sides not in Quadrant I.The angles that share the same cosine val
Oksana_A [137]

Solution:

As we know reference angle is smallest angle between terminal side and X axis.

As cosine 45 ° is always positive in first and fourth quadrant.

i.e CosФ, Cos (-Ф) or Cos(2π - Ф) have same value.

As, Cos 45°, Cos (-45°) or Cos ( 360° - 45°)= Cos 315°are same.

So, Angles that share the same Cosine value as Cos 45° have same terminal sides  will be in Quadrant IV having value Either Cos (-45°) or Cos (315°).

Also, Cos 45° = Sin 45° or Sin 135° i.e terminal side in first Quadrant or second Quadrant.
