Answer:

Area of shaded region=2 ×3.14×R -2×3.14×r(where R is lager radius and r is smaller radius.)

Therefore area of shaded region=2×3.14×12 -2×3.14×8

=2×3.14(12-8)

=6.18 ×4

=24.72 inc^2

Solve for x in each of the equations or inequalities below, and name the property and/or properties used:
nordsb [41]

Answer

a) 3/4 x = 9

    x = \dfrac{9\times 4}{3}

    x = 12

b)  10+ 3x = 5x

     2 x = 10

        x = 5

c) a + x = b

       x = b - a

d) c x = d

      x =  \dfrac{d}{c}

e)  \dfrac{1}{2} x - g < m

     \dfrac{1}{2} x< m + g

              x  < 2( m + g)

f) q + 5 x = 7 x - r

   q + r = 2 x

      x = \dfrac{q + r}{2}

Please help me find the area of this figure
Harman [31]

Answer:

=51.63 m^2

Step-by-step explanation:

First find the area of the triangle

A = 1/2 bh = 1/2(3) * 5 = 7.5

Then find the area of the rectangle

A = l*w = 5*6 = 30

Then find the area of the semi circle, which is 1/2 the area of the circle

The diameter is 6 so the radius is 3

A = 1/2  pi r^2 = 1/2 (3.14) (3) ^2 = 14.13

Add the areas together for the total area

7.5+30+14.13

=51.63
