Which of the following is equal to 5/8÷2/7?

natta225 [31]

Answer:

5/8 * 7/2

Step-by-step explanation:

Whenever you divide fractions, you can use the 'keep change flip' method.

You keep 5/8, change the division sign to multiplication, and then flip the second fraction.

1. 5/8 / 7/2 - Keep 5/8

2. 5/8 * 7/2 - Change division sign

3. 5/8 * 2/7 - Flip the second fraction, 7/2 -> 2/7

find the volume of a right circular cone that has a height of 14.7 ft and a base with a circumference of 13 ft

Doss [256]

Answer:

Volume of the cone =650.06 cubic feet

Step-by-step explanation:

Height of the cone= 14.7 feet

Circumference= 13 feet

Radius = 13/2 = 6.5 feet

Volume of the Cone:

$=\pi r^2\frac{h}{3}$

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

Putting the values in the formula:

Volume of the cone is :

$=3.14*(6.5*6.5)*\frac{14.7}{3} \\\\=3.14*(6.5*6.5)*4.9\\\\=3.14*42.25*4.9\\\\=3.14*207.03\\\\=650.06feet^3$

Volume of the cone is 650.06 cubic feet
