<span>83.03 acres. To solve this, first calculate how many square feet that central park covers. Just multiply its length and width. So 1.37x10^4 * 2.64x10^2 = 3.6168x10^6 Now divide its area in square feet by the number of square feet in an acre. 3.6168x10^6 / 4.356x10^4 = 8.303x10^1 = 83.03</span>

Prove that 25^11−5^19 is divisible by 31.
SCORPION-xisa [38]

Answer:

Divisible by 3 is the answer

Step-by-step explanation:

First get everything to have the same base of 5

25^11 - 5^19

(5^2)^11 - 5^19

5^(2*11) - 5^19

5^22 - 5^19

Now factor out the GCF 5^19 to get

5^22 - 5^19

5^(19+3) - 5^(19+0)

5^19*5^3 - 5^19*5^0

5^19(5^3 - 5^0)

5^19(125 - 1)

5^19*(124)

At this point, we factor the 124 into 31*4 to end up with this full factorization: 5^19*31*4

Therefore, 25^11 - 5^19 is equivalent to 5^19*31*4

Since 31 is a factor of the original expression, this means the original expression is divisible by 31.

What is the volume of a sphere with a radius of 3 inches? 12π cubic inches 24π cubic inches 36π cubic inches 48π cubic inches
Anni [7]

Answer:

The answer is

<h2>36π cubic inches</h2>

Step-by-step explanation:

Volume of a sphere is given by

<h3>V =  \frac{4}{3} \pi  {r}^{3}</h3>

where r is the radius

From the question

r = 3 inches

Substitute the value into the above formula and solve for the volume

That's

<h3>V =  \frac{4}{3}(  {3})^{3} \pi \\  =  \frac{4}{3}  \times 27\pi \\  = 4 \times 9\pi</h3>

We have the final answer as

<h3>36π cubic inches</h3>

Hope this helps you
