8. 4. Find the area of the circle to the nearest tenth. Use 3.14 for  .
Non-Response Grid

9. The answer is A.
Diameter is 12.2 in so the radius is 6.1 in. Area is 𝜋 𝑟 2 so 𝜋 (6.1) 2 =37.21𝜋 = 37.21(3.14) = = in2

10. 5. 𝑀𝑂 bisects ∠LMN, m∠LMO =8x 25, and m∠NMO =2x + 41
5. 𝑀𝑂 bisects ∠LMN, m∠LMO =8x 25, and m∠NMO =2x Solve for x and find m∠LMN. The diagram is not to scale.
x = 11, m∠LMN=126
x = 11, m∠LMN=63
x = 10, m∠LMN=110
x = 10, m∠LMN=55
Non-Response Grid

11. The answer is A.x = 11, m∠LMN=126
Bisects means the angles are equal so set them equal to each other and solve.
8x 25 = 2x + 41
6𝑥=41+25=66
𝑥=11
8 11 −25=63
=63
So the whole angle measures 126 degrees

18. 9. Nate wants to put a fence around his rectangular garden
9. Nate wants to put a fence around his rectangular garden. His garden measures 39 feet by 48 feet. The garden has a path around it that is 3 feet wide. How much fencing material does Nate need to enclose the garden and path?
99 𝑓𝑒𝑒𝑡
198 𝑓𝑒𝑒𝑡
150 𝑓𝑒𝑒𝑡
186 𝑓𝑒𝑒𝑡
Non-Response Grid

19. The answer is B.
48 ft
39 ft
3 ft
Since the pathway is on both sides you must add 6 to each dimension to find the new perimeter = 54 and = 45. P = 2(54) + 2(45) =198 FEET OF FENCE NEEDED.

The angle congruent to ∠𝐺𝐹𝐷 is ∠𝐷𝐹𝐸. They have the same markings.

22. 11. If Z is the midpoint of 𝑅𝑇 what are x, RZ, and RT?
Non-Response Grid

23. The correct answer is A. x = 4, RZ = 9, and RT = 18
Midpoint means middle so RZ = ZT. 8𝑥 −23=9
8𝑥=9+23=32
8𝑥=32
𝑥=4
𝑅𝑍=8 4 −23=32 −23=9
𝑅𝑍+𝑅𝑇=9+9=18
