The area of the track will be 78501 m². The area of the track is equal to the area of the circle.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.

The area of the track is found as;

$\rm A=\frac{\pi}{4} d^2 \\\\ \rm A=\frac{3.14}{4} (100)^2 \\\\ A=7850 \ m^2$

Hence, the area of the track will be 78501 m².

Solve the following (c) 60 - x² = 56

Rus_ich [418]

x
=
−
7
or
x
=
−
8

Explanation:
Find a pair of factors of
56
with sum
15
.
The pair
7
,
8
works in that
7
⋅
8
=
56
and
7
+
8
=
15

Hence:
0
=
x
2
+
15
x
+
56
=
(
x
+
7
)
(
x
+
8
)

So:
x
=
−
7
or
x
=

vagabundo [1.1K]

Answer: The percent of the people surveyed were satisfied with the car = 40% .

Step-by-step explanation:

Given: Total number of people surveyed = 3300

Number of people said that they would buy that type of car again = 1320

i.e. Number of people were satisfied with the car = 1320

The percent of the people surveyed were satisfied with the car =

$=\dfrac{1320}{3300}\times100\\\\=\dfrac{12}{30}\times100\\\\=\dfrac{4}{10}\times100\\\\=0.4\times100=40\%$

Hence, the percent of the people surveyed were satisfied with the car = 40% .
