Answer:
x = 32 is the correct answer of this question ..
Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
I'm going to assume that there is something in A1 but the way you are describing the problem, you could just as easily write a constant in the formula you are using in cells E1 to E10 and F1 to F10
The trick is to refer to A1 as $A$1 which means that E1 to E10 isn't going to get creative and start looking for things in a1 to a10.
Here is an actual table made from what I think you mean
1 113 114
2 114 116
3 115 118
4 116 120
5 117 122
6 118 124
7 119 126
8 120 128
9 121 130
10 122 132
1 to 10 on the left is in column D
A1 contains 112
In column E the enteries from 1 to 10 simply take = $A$1 + d1
Column F uses $A$1 and adds 2*d to 112
Here is the chart shown in formula form.
1 =D1+$A$1 =$A$1 + 2*D1
2 =D2+$A$1 =$A$1 + 2*D2
3 =D3+$A$1 =$A$1 + 2*D3
4 =D4+$A$1 =$A$1 + 2*D4
5 =D5+$A$1 =$A$1 + 2*D5
6 =D6+$A$1 =$A$1 + 2*D6
7 =D7+$A$1 =$A$1 + 2*D7
8 =D8+$A$1 =$A$1 + 2*D8
9 =D9+$A$1 =$A$1 + 2*D9
10 =D10+$A$1 =$A$1 + 2*D10
Remember that 1 to 10 is in d1 to d10
2 petunias leave $6.50 on her wallet, and 8 leave $5.00. This means that 6 petunias cost $1.50, and that 1 petunia costs 25 cents.
.25 goes into 3.50 (the amount of money she has left in her wallet after buying 14 petunias) 14 times. 14 + 14 =28.
Ying Ying can buy 28 petunias at most.
