The circumference of a circle is 121 pi cm, what is the area in term of pi?

1 answer:

4 0

We know that
[the circumference of a circle]=2*pi*r---------> r=[the circumference]/(2*pi)
r=121*pi/(2*pi)------> r=60.5 cm

area of the circle=pi*r²------> area=pi*60.5²-----> 3660.25*pi cm²

the answer is
3660.25*pi cm²

Give the values of a, b, and c needed to write the equation's standard form.(5 + x)(5 - x) = 7A = 1; B = 0; C = -18A = 25; B = 0

Maksim231197 [3]

We need to FOIL that out and then get it into standard form to see what our A, B, and C are. FOILing gives us $25-x^2=7$ . If we move the 7 over by subtraction and set it equal to 0, we have $-x^2+18=y$ . In order to avoid a negative leading coefficient, we can change all the signs to get $x^2-0x-18=0$ so A = 1, B = 0, C = -18, first choice above.
