The area of each circle

Katyanochek1 [597]

Answer:

8. $25\pi$ $in^2$

11. $9\pi$ $m^2$

Step-by-step explanation:

Area = $\pi r^2$

r = d/2

$\pi$ = 3.14

r = 10/2

r = 5 in

Area = $\pi 5^2$

Area = $25\pi$ $in^2$

10.

r = 6/2

r = 3 m

Area = $\pi 3^2$

Area = $9\pi$ $m^2$

Hope it helps! (:

4 - 3d = d - 8<br> solve for d

torisob [31]

Well you subtract d from both sides with would make 2D-4=-8. Then you subtract four to both sides which is -12. Then you divide -12 by 2D which is 6. D=-6

For any perfect square trinomial (quadratic), the constant term (last term) must be positive.

Ronch [10]

Answer:

For the perfect square trinomial (quadratic) i.e. $\left(x\:+\:3\right)^2$ , the constant term (last term) is positive.

Step-by-step explanation:

"Perfect square trinomials" are termed as the quadratics that are the outcomes of squaring binomials.

For example:

$\left(x\:+\:3\right)^2$

$\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a+b\right)^2=a^2+2ab+b^2$

$a=x,\:\:b=3$

$=x^2+2x\cdot \:3+3^2$

$=x^2+6x+9$

Therefore, for the perfect square trinomial (quadratic) i.e. $\left(x\:+\:3\right)^2$ , the constant term (last term) is positive.
