The figure is made up of a cylinder and 2 cones. what is the volume of the composite figure? use 3.14 for r. round to the
nearest hundredth.
4 mm
2 mm
5 mm
2 mm
recall the formulas v=bhand
mm3

  87.92 mm³

Step-by-step explanation:

The area of the base of the cylinder and cones is the same for all, the area of a circle of radius 2 mm:

  B = π·r² = 3.14·(2 mm)² = 12.56 mm²

If we call the heights of the lower cone, cylinder, and upper cone h1, h2, and h3, respectively, then the total volume is ...

  V = (1/3)Bh1 + Bh2 + (1/3)Bh3

Here is is convenient to factor out B and also 1/3, so we have ...

  V = B(h2 + (1/3)(h1 +h3))

  V = (12.56 cm²)·((5 +(2+4)/3) cm) = 7·12.56 cm³

  V = 87.92 cm³

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
