A cone has a diameter of 7.5 ft and a height of 4.25 ft. What is the volume of the cone to the nearest tenth? Use 3.14 for π.

leva [86]

Answer:

The volume of a cone is $62.5\ \text{feet}^3$ .

Step-by-step explanation:

We have,

Diameter of a cone is 7.5 ft

Radius of a cone is 3.75 ft

Height of the cone is 4.25 ft

It is required to find the volume of the cone. The formula of the volume of cone is given by :

$V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\times 3.14\times (3.75)^2\times 4.25\\\\V=62.55\ \text{feet}^3$

So, the volume of a cone is $62.5\ \text{feet}^3$ .

A triangle with an area of 45.5 cm2 has a base

FromTheMoon [43]

If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height

Step 1. 14 ÷ 2 = 7

Step 2. 45.5 ÷ 7 = 6.5

Height = 6.5 cm

$\large\boxed{f(n)=2\cdot f(n-1)+1}$

Step-by-step explanation:

$f(1)=5\\\\f(2)=11=2\cdot5+1=2\cdoy f(1)+1\\\\f(3)=23=2\cdot11+1=2\cdot f(2)+1\\\\f(4)=47=2\cdot23+1=2\cdot f(3)+1\\\\f(5)=95=2\cdot47+1=2\cdot f(4)+1\\\vdots\\f(n)=2\cdot f(n-1)+1$
