Answer:
11
Step-by-step explanation:
1/3 nr^2h = volume of a cone
1/3 x 22/7 x 14 x r^2 = 440
r^2 = 440 x 3 x 7/22 x 1/14
r^2 = 30
r = 30
r = 5
Answer:
No
Step-by-step explanation:
Let's look at an example
24
24 is divisible by 6 24/6 = 4
24 is divisible by 8 24/8 = 3
24 is not divisible by 48 24/48 = 1/2 which is not an integer
$16 because when buying a $20 shirt with the discount of 20% it would be 20-4=16
Divide the shape into 2 rectangles:
Area = Length x width
1 : 7 x 30 = 210
2: (25 -7) x (30-20) = 18 x 10 = 180
Total area = 210 + 180 = 390 square feet.
