False. Every place is close to a body of water!
Answer:
<em><u>4.19</u></em>
Explanation:
4
V= --πr^3. is formula sub. pi for 3.14
3
the sphere has a diameter of 2yds. then the radius is half that. radius (r)= 1.
radius to the 3rd power (r^3) if r=1.. then 1^3=1
4 4
V= --×π×r^3 = --×π×1^3≈4.18879
3 3
round 4.18879 to nearest hundredth = <em><u>4.19</u></em>
North America and Africa. North America’s life expectancy is around 76 for males and 81 for females. African life expectancy is around 61 for males and 65 for females
