Answer:
Use the app photomath
Step-by-step explanation:
Assume that the pillars are cylindrical..you're looking for the lateral surface area correct?
to get the lateral surface area, you use the formula LSA = 2rh(pi) where r is radius h is height
substitute the values...
h = 10
d = 1 so r =1/2
so LSA = 2 (1/2)(10)(3.14)
LSA = 10(3.14)
LSA = 31.4 sq ft :D Can You Mark Me Brainlest Plz...
The square root of a whole number will be rational if the whole number is a perfect square (i.e 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 etc) and irrational otherwise.
Rational number is a number that can be described as m/n
so a fraction can be a rational number, 0.8=4/5
Irrational numbers can't be written as a fraction
The part about the number having to be a perfect square is still correct, if it's not a prefect square than it will just keep going(a decimal that never ends)
for example the square root of 0.64 is 0.8
and the square root of 10 is 3.162277...
as you can see the 0.64 one ends and is rational, whereas the 10 one just keeps going and is irrational.
It will be equal to the number because gcf means to equal to not less that is lcm
