I don’t think so but divide the top one by the bottom one for every one of them and if it is all the same answer they are proportional x/y
Answer: number one is d and number 3 is c I think
Step-by-step explanation:
[(21 + 6) − 3^2] ÷ 9 ⋅ 2=[(27) − 9] ÷ 9 ⋅ 2
=18 ÷ 9 ⋅ 2
= 2 . 2
= 4
Circumference of the circle is given as = 220 feet
We have to find the diameter.
Circumference is found as = 2 * PI * r


r=35.03
Diameter is 2*radius
Diameter =
= 70.06
Hence, diameter of the circle is 70.06 feet.
The square root of 225 is 15 :)
