<u>Given</u>

  • r = 1.6 cm
  • h = 6.2 cm

a.

<u>Volume of the half-sphere:</u>

  1. V/2 = 1/2*4/3*πr³ = 2/3*3.14*1.6³ = 8.6 cm³ (rounded)

b.

<u>Volume of the cylinder:</u>

  • V = πr²h = 3.14*1.6²*6.2 = 49.8 cm³

c.

<u>Volume of the figure:</u>

  • V = 8.6 + 49.8 = 58.4 cm³

FORMULA:

  • Volume of hemisphere = 2/3πr³
  • Volume of cylinder = πr²h

ANSWER:

[a] Volume of half sphere = 2/3πr³

  • 2/3 × 3.14 × (1.6)³
  • 8.57cm³ or 8.6cm³ rounded.

[b] Volume of cylinder = πr²h

  • 3.14 × (1.6)² × 6.2
  • 49.8cm³

[c] Volume of whole figure = 8.6cm³ + 49.8cm³

  • 58.4cm³

Find the measure of the missing value in the
kumpel [21]

Answer:

12.6

Step-by-step explanation:

The two left sides have lengths, so this allows you to establish the ratio of the lengths of the sides of the triangles,

left triangle : right triangle

ratio = 25 : 17.5

The bottom sides are also in the same ratio.

ratio = 18 : w

Write a proportion by setting the ratios equal and solve for w.

25/17.5 = 18/w

Cross multiply.

25w = 17.5 * 18

25w = 315

w = 12.6

Answer: 12.6

Find the net change in the value of the function between the given inputs. h(t) = t2 + 2; from −5 to 8
pashok25 [27]

Answer:

39

Step-by-step explanation:

Given the function :

h(t) = t² + 2

From t = 5 to t = 8

when, t = 5

h(5) = 5² + 2

h(5) = 25 + 2

h(t) at t = 5 ; equals 27

when, t = 8

h(5) = 8² + 2

h(5) = 64 + 2

h(t) at t = 8 ; equals 66

Net Change :

h(8). - h(5)

66 - 27 = 39
