Answer:

∠RXZ and ∠YXZ is supplementary.

Step-by-step explanation:

We have to choose the pair of angles from the given options which are supplementary.

Two Angles are supplementary when they add up to 180 degrees.

As we know the linear pair are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 so linear pair of angles must add up to 180 degrees.

∠RXZ and ∠YXZ pair of angles formed on the straight line RY when line XZ intersects and angle on the straight line is 180 hence, supplementary.

Rest three pair of angles not formed on straight line.

Therefore, option 1 is correct.

Cindy is baking a 2-layer cake. The top layer has a diameter of 8 inches and the bottom layer has a diameter of 10 inches. What

Alenkinab [10]

The difference in area between the top surfaces of the two cakes is 28.26 inches²

<h3>Area of a circle</h3>

area = πr²

where

r = radius

Therefore,

area of top layer = πr²

d = 2r

r = d / 2

r = 8 / 2

r = 4 inches

area of top layer = 3.14 × 4²

area of top layer = 3.14 × 16

area of top layer = 50.24 inches²

area of the bottom layer = πr²

r = 10 / 2 = 5 inches

area of the bottom layer = 3.14 × 5²

area of the bottom layer = 3.14 ×25

area of the bottom layer = 78.5 inches²

Difference in area between the top surfaces of the two cakes can be found as follows:

78.5 - 50.24 = 28.26 inches²

Answer:

<h2>Irrational </h2>

Step-by-step explanation:

Firstly, 

According to rational and irrational,

$\sqrt{15} \: is \: irrational$

Since,

Natural numbers, Whole Numbers and Integers all come under Rational number.

Hence,

 $\sqrt{15}$ 

Is an irrational number.

Two cylinders are shown below. Which cylinder has the greater volume? Use 3.14 for π. Round to the nearest hundredth. Use the dr

Lemur [1.5K]

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

To find which cylinder has the greater volume, we need to find out the volume of each one.

As we all know that the formula used to determine the volume of a cylinder is:

V = The base area*the height

<=> V = π $r^{2}$ h (cubic units)

For example, in my attached photo, we will use this formula to find the volume of each one.

1. Cylinder A:

The base area = π $r^{2}$ = π $3.5^{2}$ = 38.46 square in

The height = 8.5 in

=> the volume of Cylinder A

= The base area*the height

= 38.46*8.5

= 326.91 cubic in

2. Cylinder B:

The base area = π $r^{2}$ = π $2.7^{2}$ = 22.89 square in

The height = 11 in

=> the volume of Cylinder A

= The base area*the height

= 22.89*11

= 251.79 cubic in

Hence, Cylinder B has the greater volume
