Answer:

D. 6.3 cm

Step-by-step explanation:

First we find the circumference of the circle. The formula for circumference is

C = 2πr

Using 3.14 for π and our value for 5, we have

C = 2(3.14)(5) = 31.4 cm

Next we find the portion of the circle represented by this sector. The angle is 72 out of 360 total degrees:

72/360 = 36/180 = 6/30 = 1/5

Multiply the circumference by this fraction:

1/5(31.4) = 6.28 ≈ 6.3 cm

Answer:

The common ratio r = 2.

Step-by-step explanation:

Now s2 = a1r and s4 = a1r^3 where a1 = first term and r = common ratio so

s4 / s2 = a1r^3 / a1r = r^2 = 32/8

r^2 = 4

r = 2.

Answer:

0.4 or $\frac{2}{5}$

Step-by-step explanation:

James spun the arrow 30 times which means 30 is the total. In other words, it's your denominator ( $\frac{x}{30}$ ). It landed on the blue section 12 times which means 12 is the part of the whole. In other words, it's your numerator ( $\frac{12}{y}$ ). Plug in the entire fraction and you get $\frac{12}{30}$ . Divide 12 by 30 and you get 0.4 or if you divide both the numerator & denominator by 6, you get $\frac{2}{5}$ . Either one works, depending on what your question asks for.
