44580 inches

Step-by-step explanation:

Given, D (diameter)= 22 inches

Therefore, r (radius)= 22/2= 11 inches

Volume= $\frac{4}{3}$ ×π×r³

= $\frac{4}{3}$ ×3.14×22×22×22

=44579.626 inches

Find the perimeter of a rectangle of which length is 5 more than the width

Leokris [45]

Answer:

the perimeter= 10+4W.

where W= the width.

Step-by-step explanation:

mathematically, perimeter (p)= 2L +2W

where L= length.and W=width

from the expression ;length is 5 more than the width

it is written as L = 5+W

substitute in the formula

P= 2(5+W)+2W

P=10+2W+2W

P=10+4W as the perimeter of the rectangle.

Nataly_w [17]

Answer:

steps below

Step-by-step explanation:

Total = 12+17+14 = 43

Without replacement:

C(12,5) / C(43,5) = (12!/5!*7!) / (43!/5!*38!) = (12*11*10*9*8) / (43*42*41*40*39)

= 95040 / 115511760

= 0.00082

≈ 0.082%

with replacement: 12/43*12/43*12/43*12/43*12/43 = 12⁵ / 43⁵
