Answer:B
Step-by-step explanation: “she counted the squares instead of using the scale” by looking at the graph the first coordinates are (4,24) and instead of doing that Willa counted the squares.
Y=25*3^x
1170=25*3^x
25*3^x=1170
3^x=1170/25
3^x=46.8
Log10(3^x)=LOg10(46.8)
x*log10(3)=log10(46.8)
x=(log10/46.8))/(log10(3))
x=1.60724585307/0.47712125472
x=3.50067375233
x=3.50

Answer:
314.159 square inches
Step-by-step explanation:
The radius is 10 in, just plug it into a formula.
10x-3(x-6)=-(x-1)
first distribute
10x -3x +18 = -x + 1
then you simplify
7 x +18 = -x +1
then you leave of when one side of x
6 x +18= +1
use opposite operation on the side with the x and do the same equation to the other side
6 x = -17
then divide
x = - 2.8333....
