Answer:
The perimeter is 43.6 cm
Step-by-step explanation:
In this question, we are tasked with calculating the perimeter of the sector.
Firstly, we define what a sector is. A sector is part of a circle which is is blinded by two radii and an arc. Hence we say a sector contains two radii.
Thus, to calculate the perimeter of the sector, we need the length of the arc added to 2 * length of the radius
Let’s calculate the length of the arc.
Mathematically, this is theta/360 * 2 * pi * r
where theta is the angle subtended at the middle of the circle which is 135 according to the question, and our radius is 10cm
Thus, we have
135/360 * 2 * 22/7 * 10 = 23.57 cm
Adding two radii to this, we have;
23.57 + 2(10)
= 23.57 + 20 = 43.57 = 43.6 cm to 1 decimal place

Answer:
<h2>
Amount of ounces of candy left = 22ounces</h2>
Step-by-step explanation:
Amount of halloween candy bought by Jack = 5pounds
Amount he gave trick = 3pounds
Amount jack ate = 10ounces
Before we can determine the amount of halloween candy that Jack has left, we need to convert the pounds to ounces in order to make the units consistent.
given 1pound = 16ounces
5pounds = 16* 5 ounces
5pounds = 80ounces
Also;
3pounds = 16*3 ounces
3pounds = 48ounces
Total amount of halloween used up by Jack = 48ounces + 10ounces
= 58ounces
Amount of ounces of candy left = Total amount of candy bought -amount used up
Amount of ounces of candy left = 80ounces - 58ounces
Amount of ounces of candy left = 22ounces
