What is the approximate volume of this tree trunk if the circumference is 26π inches and the height of the trunk is 22 inches,
den301095 [7]

Answer:

Volume = 11680.44 cubic inches

Step-by-step explanation:

Circumference of the trunk of a tree = 2πr

Here, r = radius of the trunk

26π = 2πr

r = 13 inch

Since, volume of the cylindrical trunk = πr²h

= π(13)²(22)

= 3718π

= 11680.44 cubic inches

Rectangle QRST is dilated with the origin as the center of dilation to create rectangle Q'R'S'T'.
scoundrel [369]

Answer:

Rule: dilation about the origin by a scale factor of 2

Step-by-step explanation:

Given

See attachment for QRST and Q'R'S'T

Required

The dilation rule

First, we calculate the scale factor (k)

From the attachment, we have:

QR = 4

Q'R' = 8

k, is then calculated as:

k = \frac{Q'R'}{QR}

k = \frac{8}{4}

k =2

<em>Hence, QRST is dilated by a factor of 2</em>

gayaneshka [121]

Answer:

the probability of not winning is 0.9946

Step-by-step explanation:

The computation of the probability of not winning is shown below:

The Probability of winning is

= 7 ÷ 1302

So, the probability of not winning is

= 1 - 7 ÷ 1302

= (1302 - 7) ÷ 1302

= 1295 ÷ 1302

= 165 ÷ 186

= 0.9946

Hence, the probability of not winning is 0.9946

The same is considered
