Answer:
degree = 120°
A =67 cm²
d=?
note : diameter= 2×radius
area of a circle = πr²
67=22/7 ×r²
67×7=22r²
469=22r²
r²=469/22
r²=21.32
r=4.62
diameter=2 × radius
d= 2× 4.62
d=9.24
d=9
I hope it helps :)

Answer:
42%
Step-by-step explanation:
The first step is to calculate the difference in the number of fishes from the beginning of the day to the end of the day.

= 38/90 × 100
= 0.422 × 100
= 42.2 %
= 42% ( to the nearest cent)
