A 72° sector in a circle has an area of 16.4π yd². What is the area of the circle? Use 3.14 for pi.

Dmitry [639]

The area of a sector of a circles is calculated by the equation A = πr^2 (theta/360). From the data of the sector, we determine the radius of the circle. THen, we can calculate for the area of the circle.

16.4π = πr^2 (72/360)
r = 9.06

Area of circle = πr^2
Area of circle = π(9.06)^2
Area of circle = 82π

gayaneshka [121]

Answer:

d(n) = n(n + 1)/2
n = 1 ⇒ d(1) = 1(1 + 1)/2 = 2/2 = 1, proved

d(k) + (k + 1) =
k(k + 1)/2 + (k + 1) =
[k(k + 1) + 2(k + 1)]/2 =
[(k + 1)(k + 1 + 1)]/2 =
d(k + 1)
