Answer:
6:5
Step-by-step explanation:
Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
The algae is spherical in nature
Volume of the algae =4/3 pi r³
Volume of the algae = 4/3×pi×2.5³
Volume of the algae = 62.5/3 pi
Surface area = 4pi r²
Surface area = 4pi ×2.5²
Surface area = 25pi
Taking their ratio
surface area : volume ratio
= 25pi:62.5/3 pi
= 25 × 3/62.5
= 1.2
Hence the required ratio is 12/10 which is 6:5
Not sure sorry I will look at it again though
Answer:
An acute angle is an angle less than 90°
Answer:
Step-by-step explanation:
x% of 8 = 3
x% = ⅜ =0.375 = 37.5%
3 is 37.5% of 8
Here u go the answer is 4/3
