Please help me how to figure this out I’m trying to figure out the area ASAP please

Natasha2012 [34]

Answer:

$1230.88m^{2}$

Step-by-step explanation:

Shown is one-fourth of a circle. Also, according to the picture, the radius is 28 meters.

The area for a whole circle is $2\pi r^{2}$ .

Using that information, we can find the area as if the circle was whole instead of just the fourth.

$2(\pi)(28m)^2 = 2(3.14)(784m^{2} ) = 4923.52m^{2}$

Now that we know the area of the whole circle, we just have to divide it by four to find the area of the fourth of the circle.

$4923.52m^{2} / 4 = 1230.88m^{2}$

That means that the area of the shape shown is $1230.88m^{2}$ .

I hope this helps!

-(7-9)z-6z=8(-6+2) solve for z

Sergeeva-Olga [200]

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8

Figure A is a scale image of Figure B

valina [46]

Answer:

x = 30

Step-by-step explanation:

Put in proportions $\frac{x}{45}$ = $\frac{18}{27}$

Cross multiply and get 27x = 45 x 18

OR...

27x = 810.

THEN...

divide by 27 on both sides to get 30

x = 30
