Answer:
15.13cm
Step-by-step explanation:
From that above question:
We are told that:
Lateral surface area of a right circular cone : πr√r² + h²
We are give the following parameters:
Lateral surface area = 236.64cm²
Radius = 4.75cm
We are to find the 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 = 15.12975 cm
Approximately to the nearest hundredth = 15.13cm
Answer:
x + 14.7
Step-by-step explanation:
Simply combine like terms. Constants go with each other and <em>x</em> terms go with each other.
6.2 + 8.5 = 14.7
x = x
x + 14.7
Answer:
y=2/3x-2
Step-by-step explanation:
Use property of proportion:
miles time (hs)
90 2.25
x 1
x = 90 ÷ 2.25
x = 40 miles
