Answer:
r = 22.3m circa
Step-by-step explanation:
We know that the perimeter of a circle can be calculated as follows:
p = 2
r
So half of perimeter will be:
p/2 =
r
We know that p/s = 70m, therefore:
r = 70m /
= 22.3 m circa.
Answer:
Step-by-step explanation:
okay so 40 divided by 159 equals .2515 than you are going to add 159 which gives you 159.2515 and than round that to the nearest 100
Answer:
The answer is B.
Step-by-step explanation:
The pattern seems to be counting by two.
Answer:AGC and DGH are opposite angles.
Step-by-step explanation:
So, Y+10=3x-40
Y-3x=-50-(1)
3x-40=2x
3x-2x=40
x=40
Y-3x40=-50
y-120=-50
y=-50+120
y=70
Hence, the answer is A 70°
