Well, "of" means division, which means the problem actually 4/9 / 3/4! With dividing fractions, I have an abbreviation, K.C.F. K.C.F. stands for, Keep it, Change it, Flip it. That basically means you keep 4/9, change / to *, than flip -3/4 to -4/3. You should end up with 4/9 * -4/3. Next, you should multiply these numbers, multiply the numerators together, and the denominators together. After multiplying, you should end with -16/27. There you go, -16/27 is the answer in that way. Also, "of" could mean percentage, if so, than it would be -1/3, since 4/9 of -3/4 is 0.333333...., and 0.333333.... is equal to -1/3.
Step-by-step explanation: One important property of a square is that all the sides of the square have the same length. That means, if a square has a perimeter of P, then one side must have a length of P/4 units. So for a square with a perimeter of (12x + 52) units, its sides would have a length of (12x + 52)/4 = (3x + 13) units. Therefore, the answer is C: (3x + 13) units.
Radius of cone is2.39cmor 2.4cm
volume of cone=45.19cm^3
Pi×r^2×h/3=45.19
22×r^2×7.5/7=45.19×3
r^2=45.19×3×7/22×7.5
r^2=948.99/165
r^2=5.7514545
r=2.39
Or we can say r=2.4cm
