Answer:
Step-by-step explanation:
28. Area of the circle = π
where r is the radius of the circle.
Given diameter = 14m, therefore radius = 
= 7m
Now area of the circle = 49
or = 49 * 3.14 * 3.14 = 483.12
29. Volume of cylinder = πh = π*
* 3 = 6.75π cu. feet or 21.195 cu. feet
30. A ball resembles a sphere. Volume of the sphere = 
Given diameter = 30inches; Therefore, radius = 15 inches
Now, Volume of the ball = 
= 4500π cu. inches or 14310 cu.inches
Take bus=5 times walk
b=5w
b+w=24
sub 5w for b
5w+w=24
6w=24
divide both sides by 6
w=4
sub back
b=5w
b=5(4)
b=20
bus-walk=20-4=16
answer is 16 more take the bus than walk
Answer:
look search math-way and type your problem in .
Step-by-step explanation:
yes sure, i learned this before so
1. a. make a proportion here, of percentage. 
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again, 
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
