Answer:
A=195.97 cm^2
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We are given the diameter. We need to find the radius
d= 2r
15.8 = 2r
Divide by 2
7.9 =r
Now we can find the area
A = pi * (7.9)^2
A = pi *62.41
Let pi = 3.14
A = (3.14) * 62.41
= 195.9674 cm^2
We round to the nearest hundredths
A=195.97 cm^2
Answer:
2. Division property of equality
3. x+1 = -4
4. Subtraction property of equality
5. x = -5
Step-by-step explanation:
A circle with center point N and three points A, B, C on its circumference. A line is drawn connecting the points A, N and C and the angle ANC is given as 138 degree.
B. 138°
Based on the graph, f(3) = 5 when x = 3
