The ratio of the side length of Square A to the side length of Square B is 4:9. The side length of Square A is 12 yards. What is
the perimeter of Square B?
1 answer:
A/B : 4/9 = 12/B
cross multiply
(4)(B) = (9)(12)
4B = 108
B = 108/4
B = 27
P = 4a...where a is the length of one side
P = 4(27)
P = 108 yds <=== perimeter of square B

Answer:
r = 7.7
Step-by-step explanation:
A = πr²
60π = πr²
r² = 60π/π
r² = 60
r = 7.746
Rounded to tenths:
7.7
You do the number line normal but with 11 in the front
