Answer:
r = 
r = 17.2 cm
Step-by-step explanation:
∵ The area of the circle A = πr²
∴ r² = A/π
∴ r = √(A/π)
∵ A = 54 cm²
∵ π = 22/7
∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm
Answer:
A: FG = ½GC
Step-by-step explanation:
Since AD, BC and CD are medians concurrent at G, it means G is the centroid.
Now, when median passes through the centroid, the centroid divides the median in the ratio of 2:1.
Also,that the median touches the side of the triangle at their midpoints.
Thus,by inspection, we can say that;
GD = ⅓AD
GC/FG = 2/1
Thus, GC = 2FG and FG = ½GC
BG = ⅔BE
Tbus,looking at the options given and what we have gotten in proof, we can say only FG = ½GC is correct.
Answer:
-2 : -1
-1 : -1/2
0 : 0
1 : 1/2
2 : 1
3 : 3/2
4 : 2
5 : 5/2
6 : 3
Step-by-step explanation:
Plug in whatever is on the left side of the table to the x in the equation (1/2 x)
Ex. y = 1/2 (4)
y = 2
16, 24, 32, 40, 48, 56, 64, 72, etc.
