Area formula: pi * radius * radius
Radius=1/2diameter=1/2(7)=3.5
3.5*3.5*pi=12.25pi square feet
Circumference formula: pi * diameter
7*pi=7pi feet
Your answer is: 63 is 90% of 70.
The work (if needed) is shown above :)
If you're comparing 1.435 * 10^(-3) mm to 1.435 * 10^3 mm, then the more reasonable measurement is 1.435 * 10^3 mm since,
1.435 * 10^3 mm = 1435 mm = 1.435 meters
1 meter is about 3.28 feet approximately
So 1.435 meters is slightly larger (about 4.708 feet) which is a fairly reasonable distance between the tracks on a railroad.
-------------------
Something like 1.435 * 10^(-3) mm is equal to 0.001435 mm, which is far less than 1 mm.
Part A is basically asking you for the GCF (greatest common factor) between 63 and 36. To find this you find all the numbers that can be multiplied to form each number.
36:
1 * 36
2*18
3*12
4*9
6*6
63:
1*63
3*21
9*7
The GCF is 9.
Part B is asking how much the GCF can go into each type of flower.
4 rows of geraniums
7 rows of marigolds
