The radius of a sphere is 3 inches. Which represents the volume of the sphere?
12 cubic inches
36 cubic inches
643 cubic inches
81 cubic inches

volume of sphere  =  113.14inches³  or  

      36πinces³

Step-by-step explanation:

given the radius of a sphere = 3inches

volume of the sphere = ?

π = 3.14v 0r 22/7

 recall, the formula for finding the volume of a sphere is given to be = 4/3 πr³

so,

volume of sphere  =   4/3 πr³

volume of sphere  = 4/3 ×  22/7 ×  ( 3)³

volume of sphere  =  4/3 × 22/7 × 27

volume of sphere  =  (4 × 22 × 9)/7

volume of sphere  =  113.14inches³  or  36πinces³

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

the equivalent expression are always the hardest ones but you look at the gcf also
