Reference angle of -3 radians is α= - 171° 53 min 15 sec .
We know the formula for calculating circular arc
Let l=circular arc which ic according to central angle of the circle α
l=((2R π)/360)α Let l=1 radian and R=1 (unit circle with radius R=1)
1= ((2π)/360)α => α= 360/(2π)= 180/π= 57° 17 min 45sec
Angle of the 1 radian is equal to angle 57° 17min 45sec
According to this
angle of the -3 radians = -3 ( 57° 17min 45sec) = - 171° 53min 15sec
when you count in the clockwise direction.
Good luck!!!
The weight of the spherical sculpture in pounds is approximately 251607 pounds
<h3>How to find the weight of the sculpture in pounds?</h3>
The sculpture is spherical and its made of solid bronze.
Therefore,
density = mass / volume
where
density = 7700 kg / m³
volume = 4 / 3πr³
volume = 4/ 3 × 3.14 × 1.524³
volume = 44.4574491494 / 3
volume = 14.8191497165 m³
Therefore,
mass = 7700 × 14.8191497165
mass = 114107.452817 kg
1 kg = 2.205 pounds
114107.452817 = ?
cross multiply
mass in pounds = 114107.452817 × 2.205
mass in pounds = 251606.933461
mass in pounds = 251607 pounds

Answer: 130
Explanation:
AXF = 90 (it’s a right angle and right angles are 90 degrees)
BXA = 40 (this is given)
BXF = BXA + AXF
BXF = 90 + 40
BXF = 130
