Find the angle of a sector with an area of 30 and radius 4.

Area of the sector is 4.19 sq. units

Step-by-step explanation:

Area of the sector = π r² (C/360), where r is radius and C is the central angle

⇒ Area = 3.14 × 4² × (30/360)

            = 3.14 × 16 × 1/12 = 4.19 sq. units

where is the figure

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
