hope this helps
Circumference = 43.96 cm, find radius:
Circumference = 2πr
43.96 = 2(3.14)r
43.96 = 6.28r
r = 43.96 ÷ 6.28 = 7 cm
We found out that the radius is 7 cm, find surface area:
Surface area = 4πr² = 4 (3.14) (7)² = 615.4 cm² (nearest tenth)
Answer: 615.4 cm²
Answer:
14 years
Step-by-step explanation:
Using the general growth formula
where F is future population, P is present population, n is years and r is rate in percentage.
Substituting 26000 for future population F, 19000 for present population P and 2.3% for rate
Introducing natural logarithms on both sides
n ln 1.023=ln(\frac {26000}{19000})[/tex]
n=(ln 26/19)/(ln 1.023)=13.79351958 years
Rounding off, n=14 years
