Answer:
18 cm
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ← r is the radius

2πr = 36π ( divide both sides by 2π )
r = = 18
Answer:
24 pints of blue paint used to create 40 pints of purple paint .
Step-by-step explanation:
As given
Hugo is mixing blue paint with red paint to create purple paint.
The ratio of blue to red is 3 to 2.
Let us assume that the x be scalar mutiple .
Thus
Pints of blue paint used = 3x
Pints of red paint used = 2x
As given 40 pints purple paints is made by mixing blue paint with red paint .
Than the equation becomes
2x + 3x = 40
5x = 40
x = 8
Thus
Pints of blue paint used = 3 × 8
= 24 pints
Therefore 24 pints of blue paint used to create 40 pints of purple paint .
Answer: 12.83%
Step-by-step explanation:
Given : Sam measured the height of a window frame as 5.23 feet, but the actual height was 6 feet.
i.e. Estimated height = 5.23 feet
Actual height = 6 feet
Then, the percentage of error in Sam's measurement will be :-
Hence, the percentage of error in Sam's measurement= 12.83%
