dalvyx [7]2 years ago
6 0

Answer:

Step-by-step explanation:

Actually Welcome to the Concept of the linear equations..

Here given value of x= 5 and y =1 , so we get as,

5a + b = 38 and 5b - a = 8

so, now we multiply equation no. 2 by 5 all over.

==> 25b - 5a = 40....(1)

hence adding new equation and equation no. 1

26b = 78

b = 78/26

hence b = 3 , and a = 7

ratelena [41]

Volume is a three-dimensional scalar quantity. The volume of the space between the cylinder and the two cones is 1184.43183 cm³.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the circumference of the base is 61 cm, therefore, the radius of the base will be,

Circumference = 61 cm

2πR = 61

R = 61/(2π) = 9.70845 cm

The volume of the cylinder(Outside shell) can be written as,

Volume = πR²×H

             = π× (9.70845)² ×12

             = 3553.29326 cm³

The volume of the two identical cones will be,

The volume of the cone = 2× (1/3) × π × R² × H

                                        = (2/3)×π×(9.70845²)×12

                                        = 2368.86143 cm³

The volume of the space between the cylinder and the two cones is,

The volume between space = 3553.29326 cm³ -  2368.86143 cm³

                                                = 1184.43183 cm³

Hence, the volume of the space between the cylinder and the two cones is 1184.43183 cm³.

An angle is 36⁰ less than its complement. What is the measure of the angle?
kakasveta [241]

Answer:

54º

Step-by-step explanation:

So a complimentary angle equals 90º. Come up with an equation, such as 36 + x = 90. And now all you have to do is solve.

36 + x = 90

-36         -36

------------------

x = 54

Another way is, "less" means subtract. And complimentary means two angles that equal 90º. So you can do 90 - 36 which equals 54
