Hello!
To find the total cost, we will need to multiply the cost per square meter, by the total area. To find the area we will use the formula A=<span>πr</span>². We will use 3.14 for pi.
We know that 2.1 is our radius. We will square it and then multiply it by 3.14.
2.1²=4.41
4.41(3.14)≈13.85
Our area is about 13.85. Now we will multiply by $1.70 to find the total cost. This gives us about $23.55.
The total cost of the glass would be about $23.55.
I hope this helps!
Answer:
138 fluiere, 158 ocarine, 184 viori
Step-by-step explanation:
given:
(1) fluiere + ocarine +viori = 480
(2) fluiere + ocarine =296
(3) ocarine + viori =342
din ecuatia (3) avem: viori= 342-ocarine
din ecuatia(2) avem : fluiere= 296-ocarine
in ecuatia (1) inlocuieste ce ai gasit ca sa fie o ecuatie doar cu necunoscuta ocarine: fluiere + ocarine +viori = 480
296-ocarine +ocarine+ 342-ocarine =480
296+342-480 = ocarine =158
viori = 342-158 = 184
fluiere = 296-158 = 138
