Nookie1986 [14]

Answer:

The area decreases by 1155.52 square meters

Step-by-step explanation:

a = pi * r ^ 2

d = 2 * r

r = d / 2

r = 96/2

r = 48

a1 = 3.14 * 48 ^ 2

a1 = 7234.56 square meters.

r = 88/2

r = 44

a2 = 3.14 * 44 ^ 2

a2 = 6079.04 square meters.

now we calculate the difference

a1 - a2 = 7234.56 - 6079.04

= 1155.52 square meters

Alexxandr [17]

Answer:

Sachet town is 12km from the airport

Step-by-step explanation:

In this question, we are asked to calculate the distance from sachet town to the airport.

This can be calculated by referring to a diagrammatic representation. Please check attached file.

Let’s proceed with the calculations however.

From the question, we can see that we have formed a Right angled triangle from the diagram and we need to calculate the distance x.

Mathematically;

x^2 + 16^2 = 20^2

x^2 = 20^2 - 16^2

x^2 = 400 - 256

x^2 = 144

x = sq.rt of 144

x = 12km
