Answer:
answer C is the right one
Step-by-step explanation:
Volume cylinder is area of the (round) surface * height.
The formula for the area of any circle = pi * radius²
pi * radius²
So the formula for the volume is
Volume cylinder = pi * radius² * height
radius = 15 in and height = 6 in
Substitute this in the formula and you get:
Volume cylinder = pi * 15² * 6
Volume cylinder = pi * 225 * 6
Volume cylinder = pi * 1350
so answer C is the right one
Answer:
Step-by-step explanation:
If a number can be expressed by sum of two square, only if the number can be represented by 4k + 1 form
1975 = 4*493 + 3
So, 1975 can't be a sum of two squares
Answer: im pretty sure its 3962.58
Step-by-step explanation
If you want to find the whole, you have to start by dividing 100% by 60%, so you can multiply that quotient by 3/4 to find the whole. 100/60=10/6=5/3. That means 5/3*60%=100%, so 3/4*5/3=whole. 3/4*5/3=15/12, and simplify to get 5/4, or 1 1/4. 3/4 is 60% of 1 and 1/4, or 5/4.
