X + x + 1 + x + 2 > 60
3x + 3 > 60
3x > 57
x > 57/3
x > 19

x + 1 = 19 + 1 = 20
x + 2 = 19 + 2 = 21

oldest brother can be at least 21

A cylinder soup has a radius of 1,6 in and is 5/7 in. tall what is the volume

nata0808 [166]

Answer:

$V=0.0623\ inch^3$

Step-by-step explanation:

Given that,

The radius of cylinder, r = 1/6 inch

The height of the cylinder, h = 5/7 inch

We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :

$V=\pi r^2 h\\\\=3.14\times (\dfrac{1}{6})^2\times \dfrac{5}{7}\\\\V=0.0623\ inch^3$

So, the volume of the cylinder is equal to $0.0623\ inch^3$ .
