The height of a can is 3 times its radius. If the radius of the can is 3 centimeters, what is the volume?

Semmy [17]

Answer:

170 $cent.^{3}$

Step-by-step explanation:

If the height is 3 times the radius you can find that by: 3r

r = 3.

So: 3 x 3 = 9

The height is 9 centimeters

Volume of a cylinder (can):

$V= 2\pi rh$

Plug in what we know

$V = 2 \pi (3) (9)\\V = 54\pi \\V = 169.646\\$

Rounds to: 170

Mr. Dyer is leaning a ladder against the side of his house to repair the roof. The top of the ladder reaches the roof, which is

boyakko [2]

Answer:

5 meters.

Step-by-step explanation:

Given:

Mr. Dyer is leaning a ladder against the side of his house to repair the roof.

The top of the ladder reaches the roof, which is 3 meters high.

The base of the ladder is 4 meters away from the house, where Mr. Dyer's son is holding it steady.

Question asked:

How long is the ladder?

Solution:

Here we found that a right angle triangle is formed in which base and height is given and we have to find the longest side of the triangle.

Base = 4 meters

Height = 3 meters

Length of the ladder = ?

By Pythagoras theorem:

Square of longest side = Square of base + Square of height

$(Longest\ side)^{2} = 4^{2} +3^{2}$

$(Longest\ side)^{2} = 16+9$

$(Longest\ side)^{2} = 25$

Taking root both side :-

$\sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{25}$

$Longest\ side = \sqrt[2]{5\times5} \\ Longest\ side = 5$

Thus, length of ladder is 5 meters.

Answer:

Answer: (a). 290°

${ \tt{a + 40 \degree + 30\degree = 360\degree}} \\ \\ { \tt{a + 70\degree = 360\degree}} \\ \\ { \tt{a = 360\degree - 70\degree }} \\ \\ { \boxed{ \tt{ \: \: a = 290\degree}}}$

Time taken by a randomly selected applicant for a mortgage to fill out a certain form has a normal distribution with mean value

Natali [406]

Given:

z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3

Solution:

X ~ N (8, 3)

For day 1, n = 5

P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z < =2.23) = 0.987126

For day 1, n = 6

P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z < =2.45) = 0.992857

For both days:

P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) = 0.9801
