andrew11 [14]3 years ago
4 0

Answer:

Area of the circle = 95.33feet^2

Step-by-step explanation:

Circumference of the circle=34.6 feet

Circumference of a circle= 2\pi r

           34.6=2\pi r\\\\

As, \pi =\frac{22}{7}=3.14

        34.6=2*3.14*r\\\\34.6=6.28*r\\\\34.6/6.28=r\\\\r=5.51feet

Area of the circle=\pi r^2

            =3.14*5.51*5.51\\\\=3.14*30.36\\\\=95.33feet^2

The area of the circle is 95.33feet^2

Solve this system of equations
olga_2 [115]

Answer:

D) x = 4, y = -2, z = 3

Step-by-step explanation:

x = 3z − 5

2x + 2z = y + 16

2(3z - 5) + 2z = y + 16

6z - 10 + 2z = y + 16

8z = y + 26 ---> (A)

7x − 5z = 3y + 19

7(3z - 5) - 5z = 3y + 19

21z - 35 - 5z = 3y + 19

16z = 3y + 54 ---> (B)

8z = y + 26

16z = 3y + 54

2(y + 26) = 3y + 54

2y + 52 = 3y + 54

y = -2

8z = -2 + 26

8z = 24

z = 3

x = 3(3) - 5

x = 4

the variables x and y vary inversely with a constant variation of 7. Use the variation formula, k=xy, to find why when x=9
dolphi86 [110]

1.Make y the subject

k = xy

k/x = xy/x

y = k/x

2.Substitute

y = k/x

y = 7/9

y = 0.777......

y = 0.8 (Answer)

To confirm

k = xy

k = 9 × 0.8

k = 7.2

k = 7 (constant)

Hope it helps☺
