Answer:
Step-by-step explanation:
Since the vertex is right between the vertex and the directrix, the y value of the vertex must be (3+(-1))/2=1. The x coordinate will just be the same as that of the focus, or in this case 0. This means that the vertex will be at (0,1). Since the graph opens toward the focus, it will be opening up, and since its vertex is at (0,1), it will have an equation of:

Answer:
93214.28 cm³
Step-by-step explanation:
The area of the given solid in the front side is = area of the rectangle + area of the semi circle.
= ( 40 × 30 ) + 0.5 × π × r²
= {Since radius = 0.5 × Diameter = 0.5 × 30 = 15 cm}
= 1553.57 cm².
Now the volume of the solid is given by (Area of the vertical surface × horizontal length) = 1553.57 × 60 = 93214.28 cm³ (Answer)
