Answer:
d = 25.12
Step-by-step explanation:
volume = 144 pie cm cubed
h = 9
d = (144 pie cm cubed / 9) / 2
d = 25.12
Hello,
V=π R²h=355=5*71
1) h=355 , R=√(1/π) ,V=π*(√(1/π)²*355=π/π * 355=355
2) h=5, R=√(71/π), V=π*(√(71/π))²*5=71*5=355
3) a>0,h=a, R=√(355/(πa)), V=π*(√(355/(πa)))²*a=π*355/(πa) * a=355
Answer:
what are the answer chooice bc i cant see the picture
Step-by-step explanation:
X + y = -3
<u>x - y = 13</u>
<u>2x</u> = <u>10</u>
2 2
x = 5
x + y = -3
5 + y = -3
<u>- 5 - 5</u>
y = -8
(x, y) = (5, -8)
Answer: That number is 16.
Step-by-step explanation:
n + 7 = 2n- 9 n represents the number now solve the question
+ 9 +9 add 9 to both sides
n + 16 = 2n subtract n from both sides
-n -n
16= 1n Divide both sides by 1
n= 16
Check: 16 + 7 = 2(16) - 9
23 =23
