The figure below is composed of eight
circles, seven small circles and one large
circle containing them all. Neighboring
circles only share one point, and two
regions between the smaller circles have
been shaded. Each small circle has a radius
of 5 cm.
What is the approximate area of the large
circle rounded to the nearest whole?

the answer is 175.4379

step-by-step explanation:

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
