We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²
(sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²
(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²
[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2
the answer is
the ratio is 2
The second choice is the answer
because the bigger the bottom or left number is the smaller the value unless t was like 10/10 that's bigger than them all
Answer:
The answer would be letter D. Valuable.
Answer:
4/5>3/4
Step-by-step explanation:
4/5=0.8
3/4=0.75
4/5 is grater than 3/4 by 0.5
I hope this helps!
