The area of this circle is 72 m2,
what is the area of a 45° sector of this circle?

answer:

9 m^2

step-by-step explanation:

answer:

9π m²

step-by-step explanation:

recall that a sector representing the whole circle has an angle of 360°

hence this 45° sector represents 45/360 = 1/8 of the area of the circle

area of the 45° sector = (1/8) x area of whole circle

= (1/8) x 72π

= 9π m²
