the answer is 11/7 feet because the perimeter of a circle is πr² and a semi circle is half of a circle then the formula would be 1/2 πr² 1/2×22/7×1 (it is 1 because we have divided the diameter to get radius so we derived at 11/7.
81-9X+9X-X^2= 81 - X^2
Hope it helps
Answer:
Function 1 has the greatest rate of change.
Step-by-step explanation:
The rate of change is also known as the slope.
Slope is rise over run: change in y over change in x.
Function 1's slope: 3 / 2
Function 2's slope: (0 - (-4)) / (5 - (-5)) = 4/10 = 2/5
3/2 > 2/5
Function 1 has the greatest rate of change.
C = 5/9(F - 32) = 5/9(94 - 32) = 5/9(62) = 34 4/9 C
