Answer:

Volume of new cylinder =   25446.9 mm³.

Step-by-step explanation:

Given  : A cylinder has a height of 1.2 cm and radius = 5 mm.

To find : If all the dimensions of the cylinder are tripled, what will be its new volume.

Solution : We have given that

Height of cylinder = 1.2 * 10 = 12 mm.

radius = 5 mm.

Volume of cylinder = pi * radius² * height.

Volume of cylinder = 3.14 * (5)² * 12

Volume of cylinder = 942.48 mm³.

If the dimensions are tripled

Height = 12 *3 = 36 mm

Radius = 5 * 3 = 15 mm

Volume =  pi * radius² * height.

Volume = 3.14 * (15)² * 36

Volume of new cylinder =   25446.9 mm³.

Therefore,  Volume of new cylinder =   25446.9 mm³.

Answer:

The expression that represents the number of deer in the forest is

y(x) = 50*(1.013)^x

Step-by-step explanation:

Assuming that the number of deer is "y" and the number of months is "x", then after the first month the number of deer is:

y(1) = 50*(1+ 0.15/12) = 50*(1.0125) = 50.625

y(2) = y(1)*(1.0125) = y(0)*(1.0125)² =51.258

y(3) = y(2)*(1.0125) = y(0)*(1.0125)³ = 51.898

This keeps going as the time goes on, so we can model this growth with the equation:

y(x) = 50*(1 - 0.15/12)^(x)

y(x) = 50*(1.013)^x

The stem and leaf plot shows the temperatures of patients who registered at a clinic one day. How many patients registered at th
Alex Ar [27]

Answer : 24

Explanation : As the attachment when referred for finding the number of patients registered. we have to just count the right integer part of the given plot.

As the plot describes the temperature of the patients on the left side and the number of times it was repeated.

So, the number of values is given by the number of leaves, one has to simply have to count the digits that are there on the right part of the plot
