Answer:
Step-by-step explanation:
the square root of of 35 is
5.916079783099616
The answer is no. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.
First, we determine the area of the wall before cutting out the door by multiplying the dimensions given.
area of wall = ( 9 ft)(5.25 ft) = 47.25 ft²
Then, we determine the area of the door by subtracting from the total area the area of the remaining wall.
area of door = 47.25 ft² - 26.25 ft² = 21 ft²
The two whole numbers that can be the sides of the door are 7 ft x 3 ft.
V=(4/3)pir^3
SA=4pir^2
so
V=288=(4/3)pir^3
times both sides by 3/4
216=pir^3
divide both sides by pi
216/pi=r^3
cube root both sides
6/(∛pi)=r
sub into other
sa=4pir^2
sa=4pi(6/(∛pi))^2
SA=4pi(36/(∛(pi²)))
SA=144pi/(∛(pi²))
SA=144pi∛pi/pi
SA=144∛pi
SA≈210.901 in²
