78.5= (3.14)r^2
25=r^2
5=r
So, the radius of a circle with an area is 78.5 cm^2 is 5 cm^2
Answer:
False. 2/3 is positive so therefore, it would be increasing, not decreasing.
Step-by-step explanation:
Kaitlin bought 4 pounds of coffee.
70-39.24=30.76
30.76 ÷ 7.69= 4
The answer is 7x+7/x^2+3x-10

Use Pythagoras' theorem:
a^2 + b^2 = c^2
Sub the values in:
10^2 + 10^2 = c^2
200 = c^2
Square root to find the answer:
c = 14.14
