Answer:
Volume= 27. 12inches³
Step-by-step explanation:
to solve this question lets write out the parameters given
radius of the cylinder  = 1.2 inches
height of the cylinder = 6 inches
volume of the cylinder = ?
<u>solution</u>
the fomular to find the volume of a cylinder is given to  be 
Volume= πr²h
Volume= 3.14 × ( 1.2)² × 6
Volume= 3.14 × 1.44 × 6
Volume= 27. 12inches³
 therefore the volume of the cylinder equals to 27. 12inches³
 
        
             
        
        
        
Answer:
x = 2.3
Measure of arc XY = 76° ⇒ answer (D)
Step-by-step explanation:
∵ arc XY congruent to arc YZ
∴ XY = YZ ⇒ chords subtended by equal arcs are equal
∴ 3x = 6.9 ⇒ x = 6.9/3
∴ x = 2.3
In ΔOXY
∵ OX = OY radii
∴ m∠OXY = m∠OYX
∵ m∠OXY = 52°
∴ m∠OYX = 52°
∵ The sum of angles of a Δ = 180°
∴ m∠XOY = 180 - 2 × 52 = 76°
∵ ∠XOY is central angle subtended by arc XY
∴ The measure of arc XY = m∠XOY = 76°
 
        
             
        
        
        
The answer would be y=(7/4)x-2. You just use reverse operations.
