Answer:

Length of plot, a = 200

Breadth of pot, x = 150

Total area of plot = a * x = 200 * 150 = 30000 m2

Length of single road , l = length of plot = 200

Breadth of single road , b = 3

Area covered by 3 roads = 3 * l * b = 1800 m2

Area covered by shops =  Area covered by plot  - Area covered by 3 roads  = 30000 - 1800 = 28200 m2

Rate of constructing roads  = Rs. 225 / m2

Total cost of constructing 3 roads = 225 * Area covered by 3 roads = 225 * 1800

= Rs. 405000

Step-by-step explanation:

have a good day :)

<h3>Given : </h3>

  • Radius of circle = 7 inches

<h3>To Find : </h3>

  • Circumference of circle = ?

<h3>Solution :</h3>

We are given radius, r = 7 inches

We know that :

Circumference = 2πr

⟹ Circumference = 2π × 7 inches

⟹ Circumference = 14π inches

Hence, circumference of circle is 14π inches.

Citrus2011 [14]

Answer:

3. Do Δy/Δx

Step-by-step explanation:

Do 10/3, which is an estimate. You get an answer of 3.3. Intuitively this makes sense because the slope is a constant positive value. And 1/3 is way too small of a number to describe the steepness shown

Or actually, do 3/1 because that would give the slope from x=0 to x=1. Since the slope is constant, that answer will apply for every single point on the function
