What is the area of a sector with a central angle of 255 and a radius of 18.4 m?
Igoryamba

Answer:

The answer is 753.01 m².

Step-by-step explanation:

Given that the formula of sector is θ/360×π×r² where r represents radius of circle. Then, you have to substitute the values into the formula :

area =  \frac{θ}{360}  \times \pi \times  {r}^{2}

Let θ = 255°

Let π = 3.14,

Let r = 18.4m,

area =  \frac{255}{360}  \times 3.14 \times  {18.4}^{2}

area = 753.01 {m}^{2}  \: (near.hundredth)

2(9n - 6) + 52 = 2(7n + 8)
STatiana [176]

Step-by-step explanation:

2×9n=18n

2×-6=-12

52-12+18n= 38 +18n

2×7n=14n

8×2=16

14n+16

38+18n=14n+16

subtract 14n from 14n and 18n

38+4n=16

subtract 38 from 38 and 16

4n=-22

divide each side by 4

n= -5.5
