Determine the volume of a sphere with a great circle of radius 12 cm. Question 20 options: A) 3,216.9 cm3 B) 1,024 cm3 C) 7,238.2 cm3 D) 21,714.7 cm3

Greetings from Brasil...

The volume of a sphere is given by the expression:

where R = radius

So

V = (4πR³)/3

V = (4.π.12³)/3

V = (4.π.1728)/3

V = 6912π/3

or

V = 7,238.23cm³

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

is means division by fractions
