The length of the minor arc AB is 6.3cm
kipiarov [429]4 years ago
3 0

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

PLEASE HELP 25 POINTS!

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.

Need answer ASAP! Please see screen shot.
vivado [14]

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.
