6sqrt2 for both since there equivalent
Answer:
The answer is 
Step-by-step explanation:
Assuming the snowball is a perfect sphere, then if A denotes the surface area and D the diameter then:
Differentiating wrt r we have:
We are told that 
and we want to find 
By the chain rule we have:
∴
∴
When D=10 then
The sign (-) shows that the D is decreasing.
Answer: mean = 318.3
Median =330
Mode= 200
Step-by-step explanation:
Mean (average) is the total sum of values in a given a data set ÷ number of values
= 3820/12
Mean= 318.3
Median= midpoint value in a given data set. When the data set is an even number, median is calculated with the 2 middle point values as n1 + n2/2
Step 1: we rearranged the data set from least to highest value to give
200,200,220, 240,300,320,340,360,380,400,420 and 440
Median= 320 + 340/2
=660/2 = 340
Mode is the value with highest frequency in a given data set, from the given question, mode = 200

Answer:
<h2><u><em>
(2s + 5) × (2s + 5)</em></u></h2><h2><u><em>
or</em></u></h2><h2><u><em>
(2s + 5)²</em></u></h2>
Step-by-step explanation:
A side of a square garden is represented by the expression 2s + 5. Which expression represents the area of the garden?
Area = s * s ( side x side or side²)
(2s + 5) * (2s + 5)
or
(2s + 5)²
