Answer:
153.94 cm
Step-by-step explanation:
d=2r (need radius (r) to solve for the area)
14=2r
r=7
A=πr²
A=π(7)²
A=π49
A=153.94
Answer:
Assuming that the angles of JKL and NOM are in equal order, we know that congruent angles in a congruent triangle are equal to the corresponding angles in the other triangle. And assuming that JKL has the corresponding angles in the same order as NOM, statement D is correct.
This is because KL would be equal to OM not NM, JK is equal to NO not OM, JK and KL are apart of the same triangle, and LJ does equal MN assuming the corresponding angles are in the same order.
D.

Answer:
809.69
Step-by-step explanation:
747.98(.0825)=61.708
747.98+61.708=809.688
There are various ways to solve this. I will solve by elimination which seems easier:
I multiply the top equation by 1/2 to get 1/4y so I can eliminate y:
-3x/8 + 1y/4 = -1 Now add the second equation:
1x/5 - 1y/4 = -6 This gives:
------------------------------------
-3x/8 + 1x/5 = -7 Get a common denominator:
-15x/40 + 8x/40 = -7 Now add fractions:
-7x/40 = -7 Multiply by the reciprocal(-40/7):
x = 7 × 40 / 7 Simplify:
x = 40.
Now plug in 40 for x in one of the equations and solve for y (2nd equation looks easier):
1(40)/5 - 1y/4 = -6
8 - y/4 = -6 subtract 8
-y/4 = -14 multiply by 4
-y = -56
y = 56.
So we got x=40 and y=(56) new lets check!
-3(40)/4 + (56)/2 = -2
-3(10) + 28 = -2
-30 + 28 = -2
-2 = -2.
