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)

A city has 3 new houses for every 9 old houses. If there are 21 new houses in the city, how many old houses are there?
kipiarov [429]
To find your answer you would divide 21 by 3 which would be 7, once you've got 7 you would multiply it by 9 which would give you the amount of old houses that there is which would be 63.
