L 7.8.2 Test (CST): Area, Surface Area, and Volume Question 24 of 30 Find the area of the sector of the circle below. The radius of the circle is 6 cm. Use 3.14 for at 90" O A. 18.84 cm2 O B. 4.71 cm2 O C. 28.26 cm2 O D. 6.22 cm​

28.26 cm^2

Step-by-step explanation:

Mathematically, we have the area of a sector as;

theta/360 * pi * r^2

theta is the angle subtended at the center of the circle by the sector which is 90 degrees

r is the radius of the circle given as 6 cm

Substituting these values;

90/360 * 3.14 * 6^2 = 28.26 cm^2

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )
