1) Circle A (because A is the center)

2) A minor arc is smaller than a semicircle so EF, CBF, and DEF

3) 180 = EAD + 90 + 52

   180 = EAD + 142

    38° = EAD

4) angle EAF = 180 - 60, or 120° so arc EF should be 120° (I believe)

5) arc FCE is opposite of EF so 360 - 120 = 240°

Answer: Circle A, EF is a minor Arc, EAD = 45 degrees, Arc EF= 150 Degrees, and FCE = 210 I guess from the looks of the Picture.

Volume of this prism ​
Lyrx [107]

The volume is (area of cross-section) x (length) .

-- The cross-section is a triangle.  The area of a triangle is

Area = (1/2) (base) (height) .

In this one, the base is 9/4 m and the height is 3-1/3 m .

Area = (1/2) (9/4 m) (3-1/3 m)

Area = (1/2) (9/4) (10/3)

Area = 90/24 m² .

-- Volume = (area of cross-section) x (length)

Volume = (90/24 m²) x (7-1/3 m)

Volume = (90/24) x (22/3) m³

Volume = (1,980 / 72) m³

<em>Volume = 27.5 m³  </em>
