Cual es la raiz cuadrada de 81
i can't really make a proportion, but this is the best i can do.
1 day=24 hours=1440 minutes (to convert to the same unit)
finally, distance=speed×time, so (3/4)*1440=1080 miles.
½ r² ∅
the area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle. so in the below diagram, the shaded area is equal to ½ r² ∅ .
the question has multiple answers.
