Step-by-step explanation:

> find the angle of center circle:

cos~¹ 5/(5+12) = cos~¹ 5/17 = 72°

so the sector area of the shaded

region =

(360-72)/360 × 3.14 × 5²

= 288/360 × 78.5

= 62.8

> the height of triangle (red Line) =

4×tan 72° = 4× 3.078 = 12.31

the height of pyramid (green

Line) = √12.31²-8.5² =√74.16

= 8.61

so the volume of pyramid =

⅓×(17×8)×8.61 = 390.32

1 )
 z =180 - 112   =  68 

y = 360 - 68 - 87 - 103  = 102


2 ) tan Q = 171 / 50  = h / 160     h = 171 (160) /50   
        =27310/50  = 547.2 cm

3)  5 pint = 2.36588 L

4)
 1 kg = 35.274 Oz
so, 133 oz =3.77049  = 3.77 kg

5) area =  ( 1/2 * 20 * 15) + ( 36*20 ) +  ( 1/2 * pie * r^2)       =  150 + 720 + ( 1/2 * 3.14 * 100)       = 150+720+157      = 1027  sq. cm

hope i helepd  a bit :-)
