Step-by-step explanation:
Answer:
2 cans
Step-by-step explanation:
Given that :
Radius of pool = 30 feets
Using the relation for the Area of a circle :
Area = pi*r^2
Thus,
Area of pool = 3.14 * 30^2
Area of pool = 3.14 * 900 = 2826feet²
Paints are sold in cans of 5 gallon
5 gallon of paint = 1500 feet²
Least number of 5 gallon can required :
2826 feet² / 1500 feet² = 1.884 cans
Hence,
Least number of 5 gallon can required = 2 cans
Answer:
Part A.
w = √(d^2 - l^2)
Part B.
w = 6ft
Step-by-step explanation:
length l = 8ft
diagonal d = 10ft
width w = ?
we can see it as a Trangle, so using a Pythagorean theorem,
d^2 = l^2 + w^2
w = √ (d^2 - l^2)
w = √ (10^2 - 8^2)
w = √ (100 - 64)
w = √ 36
w = 6
The third one No it’s not
Answer:
x = 26
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + 3x + 5x - 54 = 180 , that is
9x - 54 = 180 ( add 54 to both sides )
9x = 234 ( divide both sides by 9 )
x = 26
