• substitute:
Answer:
Step-by-step explanation:
To find the least common multiply, you must descompose 12 and 15 into their prime factors, as you can see below:
12=2*2*3=2²*3
15=3*5
Choose the common and non common numbers with their greastest exponents:
3*5*2²=60
Now you must choose the common and non common variables with their greastest exponents:
n³
Therefore, you can conclude that the least common multiply is:
Answer:
radius = 65 cm
Step-by-step explanation:
(See image attached for better comprehension)
To find the value of the radius, we just need to draw a triangle, where one side is half of the chord (the distance from the chord to the center creates a point that divides the chord in two equal segments), other side is the distance from the chord to the center, and the hypotenusa will be the radius.
So, using Pythagoras' theorem, we have that:
r^2 = 56^2 + 33^2
r^2 = 4225
r = 65 cm
