Se ha atado una cabra con una cuerda de 15 m de longitud, en una de las esquinas de un prado rectangular de 20x30 m. calcular la superficie del prado en el que se puede pastar la cabra

The answer in English

A goat has been tied with a rope 15 m long, in one of the corners of a rectangular meadow 20x30 m. Calculate the surface of the meadow on which the goat can graze.

we know that

the surface of the meadow on which the goat can graze is a quarter of a circle

the area of the surface of the meadow is equal to

where

r=15 m

substitute

therefore

the answer is

the area of the surface of the meadow on which the goat can graze is

The answer in Spanish

Sabemos que

la superficie del prado en el que se puede pastar la cabra  es igual al area de un cuarto de circulo

El area de la superficie del prado es igual a

donde

r=15 m

sustituya

por lo tanto

La respuesta es

El area de la superficie del prado en el que se puede pastar la cabra  es igual

okay so 15.15 *()5: +5/6

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
