Answer:
282.7 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated using the formula
V = πr²h ( r is the radius and h the height )
here r = 3 and h = 10, hence
V = π × 3² × 10 = 90π ≈ 282.7 cm³ ( to 1 dec. place )
Answer:
A. the perpendicular bisector of the line segment XY
Step-by-step explanation:
You know that one point equidistant from X and Y is the midpoint of segment XY. The third vertex of an isosceles triangle with XY as its base will also be equidistant from X and Y. That vertex will be located on the perpendicular bisector of XY.
The locus of points of interest is the perpendicular bisector of XY.

For many geometry problems, it can be helpful to draw a diagram.
Answer:
a) interest in 30 years will be $1,890
b) account balance in 30 years will be $6,390
Step-by-step explanation:
Interest = Principal · Rate · Time
= 4500 (.014)(30)
= 1,890
Total Amount = Interest + Principal
= 1,890 + 4,500
