An athlete trains on a circular track of radius 40 m and jogs 10 laps each day, 5 days a week. How far does he jog each week? Ro

mariarad [96]

Length of a circle=2πr
r=40 m
Length of the circular track=2*π*40m=80π m.

The athelete jogs each day 10 laps
1 lap-------------------80π m
10 laps------------- x
x=(10 laps * 80π m) / 1 lap=800π m

Calculate how far he jog eache week (5 days).
1 day------------------800π m
5 days---------------- x
x=(5 days*800π m)/1day=4000π m=4000m * 3.141592...≈12566,37 m

solution: 12566 m

What is the exact area of a circle with a diameter of 18 feet?

Kitty [74]

The formula for the area of a circle is

$\pi r^{2}$

We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.

$\pi 9^{2} =81 \pi$

So the answer is B, 81 pi square feet

seven out of every 8 students surveyed owns a bike. The difference between the number of students who own a bike and those who d

guajiro [1.7K]

So if x people were surveyed, $\frac{7}{8}$ people owned a bike and $\frac{1}{8}$ did not.

The difference between them is 72:
$\frac{7}{8}$ x-\frac{1}{8} [/tex] =72
so this means that
$\frac{6}{8}$ x=72

let's simplify:

$\frac{3}{4}$ x=72

and divide by 3:

$\frac{1}{4}$ x=24

and mupliply by 4:

x=96

so 96 people were surveyed
