Answer:
r = 11
Step-by-step explanation:
C = 2πr
69.08 = 2(3.14)r
69.08 = 6.28r
r = 69.08/6.28
r = 11

the sum of two digit number and the number obtained by reversing its digit is 154 if the digit differ from 4 find the number
Answer:
The number is either 95 or 59
Step-by-step explanation:
The two digit number would be;
(10a + b)
The reversal will be (10b + a)
The sum of the two is 154
(10a + b ) + (10b + a) = 154
11a + 11b = 154
11(a + b) = 154
a + b = 14 ••••••••(i)
The difference between the two digits is 4
Let’s have this as;
a - b = 4 ••••(ii)
from ii;
a = 4 + b
Substitute this into equation i
4 + b + b = 14
2b = 14-4
2b = 10
b = 10/2
b = 5
Recall;
a = b + 4
a = 5 + 4
a = 9
So we have the number as 95 or 59

Answer:
£27.50
Step-by-step explanation:
The general approach is ...
find the area to be paintedfigure the amount of paint requireddetermine the discounted cost of the paint1. The area to be painted will be the area of the four walls, less the area of the door (which is assumed to be a hole in the wall, so is not painted).
Each wall has the same dimensions, so the same area. The area of the rectangular wall is ...
A = LW
A = (3.5 m)(2.6 m) = 9.1 m²
The area of the door is ...
A = (2.2 m)(0.8 m) = 1.76 m²
Then the area to be painted is the area of the 4 walls less the area of the door:
painted area = 4(9.1 m²) -1.76 m² = 34.64 m²
__
2. Each 2 L tin of paint will cover (2 L)×(8 m²/L) = 16 m², so the number of tins needed is ...
(34.64 m²)/(16 m²/tin) = 2.165 tins
We assume this means Aisha will need to purchase 3 tins, since she will need more paint than is provided by 2 tins.
__
3. Because of the price offer on the paint, Aisha will pay full price for the first two tins, half price for the 3rd tin. That is, she will pay 2 1/2 times the full price of a tin when she buys the 3 tins of paint she needs. Each tin costs £11, so Aisha will pay ...
(2 1/2)(£11) = £27.50
Aisha will pay £27.50 for the paint to paint her living room.

Answer:
13
Step-by-step explanation:
you have to use Pythagorean Theorem which is
(a^2) + (b^2) = (c^2)
where a and be are the legs 45° from each other and c is the hypotenuse.
so just plug in the numbers
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
now square root both sides to get rid of the square on c
root(169) = root(c^2)
13 = c

The least common denominator is 12
=======================================================
Explanation:
Your teacher wants you to list the multiples of each denominator.
The multiples of 3 are: 3, 6, 9, 12, 15The multiples of 4 are: 4, 8, 12, 16, 20The values in bold are what will go in the boxes in those first two rows.
The least common denominator is 12 because it is the smallest thing found in common in the two lists above. In other words, 12 is the LCM (least common multiple) of 3 and 4. Note how 3*4 = 12. This works because 3 and 4 do not have any common factors between them other than 1.
The LCD (least common denominator) is the LCM of the denominators. The LCD is useful for when you want to add or subtract fractions. The denominators must be the same for you be able to add or subtract them.

In a class the ratio of boys to girls is 4:3 30% of the boys are left handed.
What fraction of all the people in the class are left handed boys?
6/35 fraction of people in the class are left handed
What is ratio and proportion?
Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.
Let the total no. of students in a class be x
then no. of boys in the class be 4x/7
no.of girls in the class be 3x/7
left handed boys =30%of 4x/7
= 3/10x 4x/7
=6x/35
Therefore, 6/35 fraction of people in the class are left handed

Answer:
8 x 1/6
Step-by-step explanation:
2 x 4/6 as a multiplication of a whole number and a unit fraction.
First off lets find 2 x 4/6
2 x 4/6 = 8 /6
Ok, now lets go back to the original equation.
2 x 4/6
divide 4/6 by 4 to get a unit fraction
A x 1/6
Divide 8/6 by 1/6 = 8
Or you can do A (previously known as 2) by 4 because we divide 4/6 by 4
A = 2x4 = 8
8 x 1/6 = 8/6

Answer:
A. -9, 21
Step-by-step explanation:
Use m.a.t.h.w.a.y and you will get the answer!
Answer:
A
Step-by-step explanation:
| x-6| = 15 , check if this is true for the given x values
for x= -9 we have | -9-6| = 15 true
for x= 21 we have | 21 -6| = 15 true
so A is a solution set
for x= -15 we have | -15-6| = 15 false
so B is not a solution set
for x= 9 we have | 9-6| = 15 false
so C is not a solution set
for x= -9 we have | -9-6| = 15 true
for x= -21 we have | -21-6| = 15 false
so D is not a solution set
for x= -6 we have | -6-6| = 15 false
so E is not a solution set

Answer:
C. 2, 808 cm^3
Step-by-step explanation:
Given that
The base of the pyramid is 18 centimeters
And, the height of the pyramid is 26 centimeters
We need to find out the volume of the pyramid
As we know that
The volume of the pyramid is
= 1 ÷ 3 × base^2 × height
= 1 ÷3 × 18^2 × 26
= 2,808 centimeter^3
Hence, the correct option is c.
