1: Diameter - 16 in.
Radius - 8 in.
2: 37.68 in.
3: 20 yd.
4: 0.24 mi.
5: Both students are wrong because if you use the pi instead of its abbreviated form, then the answer is about 50.27 ft.
6: The circumference of a wheel is its diameter*pi.
Answer:
x = 20
y = 10
m∡8 = 110°
Step-by-step explanation:
m∡1 + m∡2 = 180
5x + y + 3x + y = 180
8x + 2y = 180
m∡1 = m∡8 (they are alternate-exterior angles and are congruent)
5x + y = 3x + 5y
2x = 4y
x = 2y
Substitute '2y' for 'x' in 8x + 2y = 180
8(2y) + 2y = 180
18y = 180
y = 10
x = 2(10)
x = 20
m∡8 = 3(20) + 5(10) = 110°
