Step-by-step explanation:
4. the area of semi circle R =
3²/5² × 75π = 9/25 × 75π = 27π cm²
5. the ratio of their areas = 1²:7² = 1:49
Looks like all you have to do is to translate this expression into symbols:
2.1*10^9
The question is unclear but I will assume they mean 1/4 and 3 1/2.
Find common denominators.
1/4
3 1/2 -> 3 2/4
Turn into an improper fraction.
3 2/4 -> 14/4
Divide.
14/4 / 1/4
14/4 * 4/1
56/4
14
So, they can make 14 ornaments.
Best of Luck!
