Aárea do círculo mede 196 π cm². qual a medida do seu raio?

Step-by-step explanation:

The area formula for a circle is A = pi*r^2.  Solve this for the radius (raio):

r^2 = A / pi, or r = plus or minus √(A/pi).

Here, r =  +√(A/pi) = +√( 196 pi cm^2   /   pi ) = +7.9 cm.

Check:  A = pi*r^2.  Does pi*(7.9 cm)^2 = pi*196 cm^2?   Yes.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
