Use 3 to multiply the numbers
7/3*3/3
21/9
21:9
Volume of the cone: 1/3 of area of the circle * the height
(1/3)π5²*5=(125/3)π
volume of the cylinder: area of the circle *the height: π5²*10=250π
add up: (125/3)π+(125/3)π+250π≈1047.2
D is the correct answer
Answer: n=1.8
Step-by-step explanation:
6n+14=25
-14 on both sides
25-14=11
6n=11
divide 6 on both sides
n=1.83333..
Answer:
TU = 29
Step-by-step explanation:
TU + UV = TV , substitute values
9x + 2 + 5 = 14x - 8 , that is
9x + 7 = 14x - 8 ( subtract 14x from both sides )
- 5x + 7 = - 8 ( subtract 7 from both sides )
- 5x = - 15 ( divide both sides by - 5 )
x = 3
Then
TU = 9x + 2 = 9(3) + 2 = 27 + 2 = 29
