Answer:
![2 \frac{59}{72}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B59%7D%7B72%7D)
Step-by-step explanation:
3 3/8 = 3 + 3/8 = 24/8 + 3/8 = 27/8
then:
-5/9 + 3 3/8 = -5/9 + 27/8
= -40/72 + 243/72
= 203/72
203/72 = 144/72 + 59/72 = 2 + 59/72
= 2 59/72
Answer:
22123
Step-by-step explanation:
→ Find the multiplier
3% decrease = 0.97
→ Multiply the population by the multiplier which is to the power of years
30000 × 0.97¹⁰ = 22122.7 = 22123
For question one, you would need to use the formula pi r ^2. So first you have 4.5, which is your radius(stands for r). Then you square it, which is 20.25. Then, you multiply 20.25 with pi. Then for circumference, you do 2 x pi x the radius which is 4.5. So for area, you get 63.62. Then for circumference you get 28.27.
For question 2, it is basically the same steps but instead you a diameter, not a radius. To get the radius, divide by 2, which the radius will be 6. Then from there, the radius is 6, and you solve the question.
