Diameter= 9
Radius= 4.5
Area= radius*radius* pi
Area= 4.5*4.5*3.14

Answer:
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
Step-by-step explanation:
Let the weight of pineapple be x grams and weight of orange by y grams.
Now, weight of a pineapple = 7 (weight of an orange)
∴ x = 7y
Also, x = y + 870 (∵ pineapple weighs 870 more than pineapple)
Substituting the value of x in above equation,
7y = y + 870
7y - y = 870
6y = 870
y = 870/6 = 145
Weight of an orange = 145 grams
Weight of pineapple = 7 × 145 = 1015 grams
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
Answer:
What percentage of pick-up truck drivers want their next vehicle purchase to be another pick-up truck?
Should the speed limit be decreased on the highway connecting two large cities?
How many pedestrians would use a walkway built over a busy road?
Step-by-step explanation:
We use samples when using an entire population is not feasible.
It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks. This means we should use a sample.
Many people drive a highway that connects two large cities. It is not reasonable to survey every person that drives it, so we should use a sample.
On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
