For an art project, pedro uses clay to make 4 balls, each with a diameter of 4 in. what is the total volume of the 4 balls of clay? select from the drop-down menu to correctly complete the statement. the total volume of all 4 balls is about in³.

33 100 134 402

134

Step-by-step explanation:

The general formula for the volume of a sphere:

V = πr³

Given that each ball has a diameter of 4in, to find the radius, you divide by 2:

4/2 = 2 in.

One sphere:  π2³ = (3.14)(8) = 33.5

All 4 balls:  (33.5)(4) ≈ 134 in ³

Here's the correct answer for k12. C- 134). I took the test

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
