The correct answer would in fact be 52
Answer:
113.1 cm²
Step-by-step explanation:
we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius
so first, we need to find the radius
the length of the radius is half the length of the diameter
so that means that r=d/2
r=d/2
r=12/2
r=6
therefore the length of the radius is 6
now square 6, which is the same as multiplying it by itself
6²=36
now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7
so if we were to do 22/7 for instance,
36*22/7≈113.14
round that to 113.1
there's your answer :)
Hope this helps!
25 to 45 can also be written as 25/45
Both numbers are divisible (can be divided by) 5
25 divided by 5 = 5
45 divided by 5 = 9
So 25/45 = 5/9
They are equivalent fractions because they’ve been divided by the same, shared number
Answer:(-x-1)(x-4)
Step-by-step explanation:
factor the equation (multiples of 4 are 1 and 4 and 2 and 2) 4-1=1 so the factor you want to use are 1 and 4
-1(x +1)(x-4) -- -4+1=3
distribute the -1 into the first factor
(-x-1)(x-4)
180 - 78 = 102 hope this help
