Answer:
All the left numbers of the Ratio go by 8's times tables and all the right numbers go by 5's times tables
Step-by-step explanation:
8x1= 8
8x2 =16
8x3 = 24
5x1= 5
5x2= 10
5x3= 15
Let me know if its right.
Area = r^2 x PI
to find r take the square root of the area:
r = √100 = 10
The circumference of a circle is the diameter times PI.
The diameter is 2 times r = 2 x 10 = 20
The circumference = 20PI m
The answer is C.
131.88 or jus do radius times 2 so 21+ 21 = 42.
42 x pi(3.14) = 131.88
The answers should be A and E! Hope it helps!
