Hi there!
The total surface area (tsa) of a cone can be calculated with this formula :
TSA = (
× r × slant height) + × r²
The "r" stands for "radius". The radius is equal to half the diameter, so in order to be able to use the formula, you'll need to divide the diameter by 2 to find the radius :
5 ÷ 2 = 2.5 = radius
Since the slang height is in meters, you'll need to transform it into centimeters in order to have both values in centimeters. To do so you'll need to use the cross product method :
1 m = 100 cm
4 m = x cm
(100 × 4) ÷ 1 = x cm
400 ÷ 1 = x cm
400 = x cm → The slant height is 400cm.
Now replace all the information in the formula and calculate everything :
TSA = ( × 2.5 × 400) + ( × 2.5²)
TSA = ( × 1,000) + ( × 6.25)
TSA ≅ 3,141.59 + 19.63
TSA ≅ 3,161.22 cm²
There you go! I really hope this helped, if there's anything just let me know! :)
The box plot showing the five-number summary of the data in the dot plot is shown in the image attached below (see attachment).
<h3>What is a Box Plot?</h3>
A box plot shows the five-number summary of a data distribution which includes:
- Minimum value
- Maximum value
- Median
- Upper quartile (Q3)
- Lower quartile (Q1)
To create a a box plot for the data, we need to state out each data point given in the dot plot, which are:
2.3, 2.4, 2.4, 2.5, 2.6, 2.6, 2.7, 2.7, 2.8, 2.8
The five-number summary of the data points stated above would be:
- Maximum value - 2.8
- Median - 2.6
- Upper quartile (Q3) - 2.7
- Lower quartile (Q1) - 2.4
Therefore, the box plot showing the five-number summary of the data in the dot plot is shown in the image attached below (see attachment).

Answer:
Step-by-step explanation:
abs(-54) = 54.
The absolute value of any number is the positive value.
well there is 7x4, 14x2, and 28x1 of course.
