Find the are of the shape below
skelet666 [1.2K]

Answer:

Area is 235

Step-by-step explanation:

Split the shape evenly so 11 x 14 and 9 x 9then multly and add

when slpitting up the number some times you have to add or subtract so to get 9 x 9 we just take 20 then take away 11 due to the line going through 20 and 20 - 11 = 9

9 x 9 = 81

11 x 14 = 154

81 + 154 = 235

or

Simular to the first one but the cutting line is different. this time the line cuts through 14

9 x 20 = 180

11 x 5 = 55

180 + 55 = 235

Multiple of pi plis xxx
Stella [2.4K]
 \pi is an irrational number i.e. it cannot be written in the form of \frac{p}{q} where p and q are integers and q is never equal to 0.

By multiples of \pi, we can write like:

1\pi = \pi = 3.14
2\pi = 2*3.14 = 6.28
3\pi = 3*3.14 = 9.42
In the same way, any integer n when multiplied by \pi, is a multiple of \pi
