If you have a circle with an area of 49π cm² and the measure of arc AB is 60°, what is the area of the sector formed by this arc?
A) 25.7cm³
B) 25cm³
C) 8.2cm³
D)4712.4cm³

PLEASE SHOW WORK!

A)  25.7

Step-by-step explanation:

Area of a circle = π

Area of the circle in question = 49π

Equate the two equations

π = 49π

Area of a sector = ∅/360 *  π

Area of the sector with angle 60°

= 60/360 * 49π

= 25.7

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
