Answer:

Lateral Surface Area = 94.25 cm²

Surface area = 150.8 cm²

Step-by-step explanation:

A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?

Step 1

We have to find the radius of the cylinder

We are told in the question that:

The circumference of one circle is 18.84 cm

Circumference of a circle = 2πr

18.84cm = 2πr

r = 18.84/2π

r = 2.9984791279cm

Approximately the radius = 3cm

Step 2

We find the Lateral Surface Area of the Cylinder

The formula =2πrh

r = 3cm

h = 5cm

=2×π × 3 × 5

= 94.24778 cm²

Approximately = 94.25 cm²

Step 3

We find the Surface Area of the Cylinder

The formula =2πr(r + h)

r = 3cm

h = 5cm

=2×π × 3 × 5(3 + 5)

= 150.79645 cm²

Approximately = 150.80 cm²

3z + 2(z - 3) = 7z + 12

3z + 2(z - 3) = 7z + 12

3z + 2z - 6 = 7z + 12

3z + 2z - 7z = 12 + 6

5z - 7z = 18

-2z = 18

z = 18/2

z = 9

3z + 2(z - 3) = 7z + 12

3z + 2(z - 3) = 7z + 12

3z + 2z - 6 = 7z + 12

3z + 2z - 7z = 12 + 6

5z - 7z = 18

-2z = 18

z = 18/2

z = 9

Answer:

y= 3x +2

Step-by-step explanation:

-10x-30y = 6

-30y = 10x +6

y = -1/3x - 1/5

m = -1/3 perpendicular slope would be 3

2x+9y = 18

2(0) +9y = 18

y = 2 = y intercept

y = 3x +2

Answer:

the quotient of a number y and negative three point six is less than six point five.

The equation of the function is y = 4x + 5. Find the value of y when

x = 3

x = -2

y = 4x + 5 [Equation]

The value of y when x = 3 , x = -2

y = 4x + 5 [Given equation]

[tex] \therefore [/tex] When x = 3 ,

y = 4 × 3 + 5 [Value of x is 3]

y = 12 + 5

Again, when x = -2 ,

y = 4 × (-2) + 5 [Value of x is -2]

y = -8 + 5

Answer:

Half of 8 is 4 and one third of 12 is 4

Step-by-step explanation:

6/4 = 1.5   ( proportion 1.5)

804(1.5) = 1,206

Answer:

a) Opposite sides are congruent and all interior angles are right angles, hence the quadrilateral is a rectangle

b) Opposite sides are parallel and all sides are congruent, hence the quadrilateral is a rhombus

c) All sides are congruent and all interior angles are right angles, hence the quadrilateral is a square

d) m∠AEB = 90° as the diagonals are perpendicular to each other

e) m∠EAD = 90°/2 = 45° as the diagonals of a square are bisectors of the angles at the vertices

[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]

[tex](b)[/tex]

[tex]Pattern = 972,324,108,36[/tex]

Step-by-step explanation:

Given [Missing from the question]

[tex]Pattern: 2187, 729, 243, 81[/tex]

Solving (a): Continue the pattern using the divide by 3 rule

To do this, we simply divide the last term by 3, to get the next term.

So, we have:

[tex]81/3 = 27[/tex]

[tex]27/3 = 9[/tex]

[tex]9/3 = 3[/tex]

[tex]3/3 = 1[/tex]

So, the pattern is:

[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]

Solving (b): 4 terms of a different pattern using the same rule.

Let the first term be: 972

So, the next three terms is:

[tex]972/3 =324[/tex]

[tex]324/3 = 108[/tex]

[tex]108/3 =36[/tex]

So, the pattern is:

[tex]Pattern = 972,324,108,36[/tex]

1.The Chord Intersection Theorem:

If 2 chords of a circle are AB and CD and they intersect at E, then

AE * EB = CE * ED.

Problem.

Two Chords AB and CD intersect  at E.  If AE =  2cm , EB = 4 and CE = 2.5 cm, find the length of ED.

By the above theorem : 2 * 4 = 2.5 * ED

ED = (2 * 4) / 2.5

= 3.2 cm.

2.1. A given chord on a circle is perpendicular to a radius through its center, and it is at a distance less that the radius of the circle.

2. A circle of center O has a radius of 13 units. If a chord AB of 10 units is drawn at a distance, d, to the center of the circle, determine the value of d.

3. From question 2, the radius = 13 units, length of chord = 10 units and distance of chord to center of the circle is d.

A radius that meet the chord at center C, and divides it into two equal parts.

So that;

AC = CB = 5 units

Applying Pythagoras theorem to ΔOCB,

OC = d, CB = 5 units and OB = 13 units

=  +  

169 = 25 +  

169 - 25 =  

144 =  

⇒ d =  

      = 12 units

Therefore, the chord is at a distance of 12 units to the center of the circle

To Obtian the possible dimensions of the array :

List out the factirs of 54 and use a pair of each in multiplication to obtain 54 ; Theb number of multiplication pairs obtained is the number of possible dimensions of the array :

Factors of 54 : 1, 2, 3, 6, 9, 18, 27, 54

Muliplication pairs :

(6 * 9) = 54

(18 * 3) = 54

(27 * 2) = 54

(54 * 1) = 54

Hence, there are 4 possible dimensions of the array

The  expressions have an estimated quotient of 200 are C 1990 ÷ 9 and E 9795 ÷ 51 ​

Quotients are the number that is obtained by dividing one number by another number. We can use the fact that division can be taken as multiplication but with the denominator's multiplicative inverse.

We have been given that  expressions  as

A 734 ÷ 6

= 367/2

= 133.5

B 803 ÷ 10

= 80.3

C 1990 ÷ 9

= 221.1

D 5280 ÷ 48

= 110

E 9795 ÷ 51 ​

= 192.05

Hence, the expressions have an estimated quotient of 200 are C 1990 ÷ 9 and E 9795 ÷ 51 ​
