Answer:
15.13 cm
Step-by-step explanation:
We are given:
Lateral surface area of a right circular cone : πr√r² + h²
From the question, we know that:
Lateral surface area = 236.64cm²
Radius = 4.75cm
Height = ?
Making h the subject of the formula
h = √[(A/r)² - πr²]/π
h = √[(236.64/4.75)² - π ×4.75²]/π
h = √(2481.9275169 - 70.882184247)/π
h = 15.12975 cm
Approximately to the nearest hundredth = 15.13cm
Answer:
6/11 or .54
Step-by-step explanation:
What you do is you take the number of white shirts and black shirts and add them together. That equals 12.
The number of shirts all together is 22. What you do is put it into a fraction 12/22.
You will then reduce that to get 6/11.
6/11 or .54 is your answer.

Answer:
-6
Step-by-step explanation:
12(5+2y) = 4y - (6-9y)
60+24y = 4y-6+9y
24y + 60 = 13y - 6
24y-13y = -6-60
11y = -66
y = -6
Answer:
<h2>
</h2>
Step-by-step explanation:
-4÷2 = -2
8÷(-4) = -2
-16÷8 = -2
So this is a geometric sequence with the first term of 2 and a common ratio of -2
the nth term of a geometric sequence:
Therefore:
