The answer is B, I believe.

My previous teachers would always say "If its 5 and above bump up, 4 and below, bump down."

12.75

There's a 5, which means you need to bump up. So, it's 12.8.

Sorry if it isn't correct, but I hope I helped! :-)

The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13

Iteru [2.4K]

Answer:

283 cm^2

Step-by-step explanation:

Solution:-

We have a cone with a circular base of radius r = 5 cm

The height of the cone is h = 12 cm

The slant height of the cone is L = 13 cm

We are to determine the surface area of the cone. The surface area of the cone is comprised of two parts:

Base Area : Circle

$A_1 = \pi r^2\\\\A_1 = \pi 5^2\\\\A_1 = 25\pi$

Curved Surface: conical

$A_2 = \pi * r*L\\\\A_2 = \pi * 5*13\\\\A_2 = 65\pi$

The total surface area of the cone can be written as ( A ):

$A = A_1 + A_2\\\\A = (25 + 65 )*\pi \\\\A = 90*(3.14) \\\\A = 282.7433 cm^2$

Answer: The surface area of the cone to nearest whole number would be 283 cm^2

Answer:

6 is the median

Step-by-step explanation:

1, 4, 4, 5, 5, 5, 6, 6, 7, 7, 7, 8, 8, 9, 11

The median is the middle number of the data when arranged from smallest to largest

There are 15 numbers

15/2 = 7.5

Rounds to 8

A rectangular carpet has a perimeter of 274 inches. The length of the carpet is 95 inches more than the width. What are the dime

GrogVix [38]

Answer:

Length: 116

Width: 21

Step-by-step explanation:

Let's say that the width of carpet is x. If the length of the carpet is 95 inches more than the width, then let's say that the width is x + 95.

Since we are solving for the perimeter, you have to multiply the width and the length(x and x + 95) by two.

So,

2x + 2x + 190 = 274.

Simplify this and you get:

4x= 274 - 190

4x = 84

x= 21

So, the width is 21. This means that the length is 21 + 95.

21 + 95 = 116
