The sum of the two areas of two circles is the 80x square meters. Find the length of a radius of each circle of them is twice as

Alborosie

Answer:

$r = 4m$ --- small circle

$R =8m$ --- big circle

Step-by-step explanation:

Given

$Area = 80\pi\ m^2$ -- sum of areas

$R = 2r$

Required

The radius of the larger circle

Area is calculated as;

$Area = \pi r^2$

For the smaller circle, we have:

$A_1 = \pi r^2$

For the big, we have

$A_2 = \pi R^2$

The sum of both is:

$Area = A_1 + A_2$

$Area = \pi r^2 + \pi R^2$

Substitute: $R = 2r$

$Area = \pi r^2 + \pi (2r)^2$

$Area = \pi r^2 + \pi *4r^2$

Substitute $Area = 80\pi\ m^2$

$80\pi = \pi r^2 + \pi *4r^2$

Factorize

$80\pi = \pi[ r^2 + 4r^2]$

$80\pi = \pi[ 5r^2]$

Divide both sides by $\pi$

$80 = 5r^2$

Divide both sides by 5

$16 = r^2$

Take square roots of both sides

$4 = r$

$r = 4m$

The radius of the larger circle is:

$R = 2r$

$R =2 * 4$

$R =8m$

Vedavit walks his dog the same distance each day. After 5 days, he has walked his dog 1 mile. How many feet does he walk his dog

posledela

Answer:

$1056 ft$

Step-by-step explanation:

''Vedavit walks his dog the same distance each day.''

After 5 days,he has walked his dog 1 mile.''

First we are going to convert the total distance (1 mi) to feet.

The relation is :

$1mi=5280 ft$

After 5 days, he has walked his dog 5280 ft.

The next step is to divide the total distance for the amount of day that he has walked his dog (we do this because Vedavit walks his dog the same distance each day)

$\frac{5280ft}{5 days} =1056\frac{ft}{day}$

Finally, he has walked his dog $1056 ft$ each day
