What is the volume of a right circular cone if the circumference of the base is 125.6 ft and the height is 75 ft.? Use π=3.14 an

Alex_Xolod [135]

Answer:

The volume of a right circular cone is $31400\ \text{feet}^3$ .

Step-by-step explanation:

The circumference of the base of a right circular cone is 125.6 ft.

Height of cone is 75 ft.

Circumference of base is :

$C=2\pi r$ , r is radius

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{125.6}{2\times 3.14}\\\\r=20\ ft$

The volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\times 3.14\times (20)^2\times 75\\\\V=31400\ \text{feet}^3$

So, the volume of a right circular cone is $31400\ \text{feet}^3$ .

Solve the equation. <br> 4 (6 – x) + 4 = 2 (3x + 1) - 6

PtichkaEL [24]

Answer:

x = 2.4

Step-by-step explanation:

Simplify.

24 - 4x + 4 = 6x + 2 - 6

Combine like terms (24 + 4 = 28, sorry for the confusion!)

28 - 4x = 6x - 4

Add x and add 4 to both sides.

10x = 32

x = 3.2
