Answer:

2886.34 mm

Step-by-step explanation:

The radius of the disc is given to be 35 millimeters. This means that the distance from the edge of the large circle to the center is 35 millimeters.

We need to find the large circle area and subtract the small circle area from it.

Large circle area:

Area = πr^{2}

        = π(35 mm)^{2}

        = 1225π

The radius of the small circle is half the radius of the large circle. 35/2 = 17.5

Small circle area:

Area = πr^{2}

        = π(17.5 mm)^{2}

        = 306.25π

Large circle - small circle =

1225π - 306.25π = 918.75π

                            = 2886.3<u>4</u> mm

    8 x 9 = 72m^2

Then, find the area of the missing section.

    3 x 4 = 12m^2

Finally, subtract 12m^2 from 72m^2 and you get 60m^2

Let f(x)= 7-2x Find a. f(4) b. f(h) c. f(4) + f(h) d. f(3+h)
anyanavicka [17]

Step-by-step explanation:

a) f(4) = 7-2(4)

= -1

b) f(h) = 7-2(h)

= 7-2h

c) f(4) + f(h) = -1 +(7-2h)

= 6-2h

h = 3

d) f(3+h) = 7-2(3+h)

= 7-6-2h

= -1-2h

2h= -1

h = -1/2

p/s = if the real answer is different with my answer, tell me also please. Im just a student that still learning.
