It's A ...cos (90- theta) = sin theta
so A
The answer is 9/5 as 3×3 is 9 and you are dividing it by 5.
First you need to find how much is left in the container by finding the whole volume.
cylinder volume= πr²h where r is the radius and h is hight
V= (3.14)*(5²)*(10)
V=(31.4)(25)
V=785cm³ is the total volume
now half has been used so divide that number in half
785/2= 392.5cm³
now she uses 4cm³ a day so divide
392.5/4= 98.125
round to the nearest whole number
answer is B 98
Area is length x width
24 x 18 = 432
The area is 432 feet
hope this helps
