Answer :

Answer:

Part 1: The fractional part of the circumference is 1/4.

Part 2: 100.53 or 100.48 if you use 3.14 as pi

Step-by-step explanation:

Part 1: A circle is 360 degrees and a right angle is 90, so the fractional  part is 90/360 or 1/4.

Part 2: 0.5pi*r is the length of the arc. The radius, or r, is 16 cm, a half of 32. It is 2 * pi * 16 = 32 * pi. 32 * pi = 100.53 or 100.48 if you use 3.14 as pi.

The answers are 1/4 and 25.12 m.

What is length of sector?

The arc length of a circle can be calculated with the radius and central angle using the arc length formula, Length of an Arc = θ × r

Given:

d=32 m

r= 16 m

angle = 90

a) fractional part of the circle’s circumference is AB = 90/360 = 1/4

b) Length of arc = [tex]\theta[/tex]/360* 2πr

=90/360 * 2 * 3.14 * 16

= 3.14*8

= 25.12 m
