icang [17]

Answer:

$P(Red) = \frac{7}{25}$

Step-by-step explanation:

Given

$Red = 35$

$Blue = 40$

$Green = 50$

Required

Determine the probability of red

$P(Red) = \frac{n(Red)}{Total}$

Substitute value for n(Red) and calculate Total

$P(Red) = \frac{35}{35 + 40 + 50}$

$P(Red) = \frac{35}{125}$

Divide numerator and denominator by 5

$P(Red) = \frac{7}{25}$

Find the volume of the cylinder. Either enter an exact answer in terms of π or use 3.14 for π

Alex787 [66]

Answer:

Volume of the cylinder = $62.80 units^3$

Step-by-step explanation:

Height of the Cylinder(h)=5 units

Radius(r)=2 units

Volume of a cylinder= $\pi *r*r*h$

Putting the values in the formula;

Volume of the cylinder $=\pi *2*2*5$

As, $\pi =\frac{22}{7}=3.14$

Volume of the cylinder= $3.14*2*2*5$

$=3.14*2*2*5\\\\=3.14*4*5\\\\=3.14*20\\\\=62.80units^3$

The Volume of the cylinder is $62.80 units^3$
