OAB is a sector of a circle <br>what is the area of the sector
oee [108]

Answer:

12.56 square cm

Step-by-step explanation:

Central \:angle \:(\theta) = 40°\\Radius \: (r) = 6 cm

Let A be the area of the sector of circle.

\therefore \: A =  \frac{\theta }{360 \degree}  \times \pi {r}^{2}  \\  \\=  \frac{ 40 \degree}{360 \degree}  \times 3.14\times {6}^{2}  \\  \\    =   \frac{ 1}{9}  \times 3.14 \times  36 \\  \\  =   3.14 \times 4 \\ \\ = 12.56 \:  {cm}^{2}

Explain the relationship between variance and standard deviation. Can either of these measures be negative? Explain.
jarptica [38.1K]
<span>Standard deviation is the square root of variance. Variance is always a non-negative number, since you can't take the square root of a negative number. So neither can be negative </span>

Formulas for surface area and volume of a rectangular prism (this is a cube, which is a special kind of rectangular prism; the same formulas can be used for both types of figures):


S.A. = 2(wh + lw + lh), where w is the width, h is the height, and l is the length

V = lwh; likewise, w is width, h is height, and l is length


Our width, length, and height are as follows:


w = 8

l = 8

h = 8


Plug these values into each formula and solve.


S.A. = 2(wh + lw +lh)

S.A. = 2(8(8) + 8(8) + 8(8))

S.A. = 2(64 + 64 + 64)

S.A. = 2(192)

S.A. = 384


V = lwh

V = 8 * 8 * 8

V = 512


Answer: S.A. = 384 cm²; V = 512 cm³.


98.


This is also a rectangular prism, so the same formulas will be used.


Width, length, and height:


w = 2

l = 12

h = 3


S.A. = 2(wh + lw + lh)

S.A. = 2(2(3) + 12(2) + 12(3))

S.A. = 2(6 + 24 + 36)

S.A. = 2(66)

S.A. = 132


V = lwh

V = 12 * 2 * 3

V = 72


Answer: S.A. = 132 in²; V = 72 in³.

Formulas for S.A. and V of a right cylinder:


S.A. = 2πrh + 2πr², where r is the radius and h is the height

V = πr²h; r is the radius and h is the height


Radius and height:


r = 7

h = 3


S.A. = 2πrh + 2πr²

S.A. = 2π(7)(3) + 2π(7)²

S.A. = 42π + 2π49

S.A. = 42π + 98π

S.A. = 140π or approx. 440


V = πr²h

V = π(7)²(3)

V = π49(3)

V = 147π or approx. 462


Answer: S.A. ≈ 440 cm²; V ≈ 462 cm³.


100.


Same formulas as above. Notice we're given the diameter of the cylinder, however, rather than the radius. The radius is half the diameter, so the radius is 4.5 mm.


Radius and height:


r = 4.5

h = 13


S.A. = 2πrh + 2πr²

S.A. = 2π(4.5)(13) + 2π(4.5)²

S.A. = 117π + 2π20.25

S.A. = 117π + 40.5π

S.A. = 157.5π or approx. 495


V = πr²h

V = π(4.5)²(13)

V = π20.25(13)

V = 263.25π or approx. 827


Answer: S.A. ≈ 495 mm²; V ≈ 827 mm³.
