Here we are give the value for π and Diameter of the circle fence

π=3.14

Diameter = 16

Radius = Diameter/2

2πr = 2(3.14)(8)

Circumference = 50.27

Now to fine the square fence length so we do 16*4 = 64

64-50.27 = 13.73 in

Therefore, the square fence is 13.73 inches longer than the circle fence

Write each sum using summation notation 12 + 22 + 32 + 42 + ⋯ + 10000^2

Murljashka [212]

Answer:

50,00,70,000

Step-by-step explanation:

The given sequence is Arithmetic Progression.

Arithmetic Progression is a sequence in which every two neighbor digits have equal distances.

Here first we will find the number of terms

For finding the nth term, we use formula

aₙ = a + (n - 1) d

where, aₙ = value of nth term

a = First term

n = number of term

d = difference

Now, In given sequence: 12, 22, 32, 42, ⋯ , 100002

a = 12, d = 10, n = ? and aₙ= 100002

∴ 100002 = 12 + (n - 1) × (10)

⇒ 99990 = 10(n - 1)

⇒ n = 10000

Now using the formula of Sum of Arithmetic Sequence,

Sₙ = n÷2[2a + (n - 1)d]

⇒ Sₙ = (10000÷2)[2 × 12 + 9999 × 10]

⇒ Sₙ = 5000 [ 24 + 99990]

⇒ Sₙ = 5000 × 100014 = 50,00,70,000

Solve the equation. 2ª = 0.36 O + or - 0.5 O+ or - + or - 0.6 + or -0.7 06 please answer quickly

PolarNik [594]

Answer:

2nd answer is correct.

Step-by-step explanation:

z² = 0.36

z² = $\frac{36}{100}$

z² = $\frac{6 * 6}{ 10 *10}$

z = ± √ ( $\frac{6 * 6}{ 10 *10}$ )

z = ± $\frac{6}{10}$

z = ± 0.6

Therefore,

z = + or - 0.6
