A cylinder has a volume of 245 cubic units and a height of 5 units. The diameter of the cylinder is
frutty [35]

The independent variable here is b, the number of mats; the dependent var. is p, the cost of b mats. Thus, p = f(b).


Here, 245 units^3 = pi*r^2*(5 units), or


245 units^3

r^2 = ------------------- = 15.61 units^2. Thus, the radius is sqrt(15.61 units^2), or

5(3.14) units 3.95 units. The DIAMETER is d = 2*r = 7.90 units.

15/20 times 1/4 thank me if u like brainly
MaRussiya [10]

Answer: 3/16

Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.

\frac{15}{20} × \frac{1}{4} = ?

15 × 1 = 15

20 × 4 = 80

\frac{15}{20} can be reduced by dividing both the numerator and denominator by the Greatest Common Factor which is 5.

15 ÷ 5 = 3

80 ÷ 5 = 16

Therefore, \frac{15}{20} × \frac{1}{4} = \frac{3}{16}
