24π=2π(r^2+r) solve for r

Novay_Z [31]

Answer:

r=3

Step-by-step explanation:

24π=2π(r^2+r)

Divide each side by 2 pi

24π/2π =2π/2π(r^2+r)

12 = r^2 +r

Subtract 12 from each side

12-12 = r^2 +r -12

0 = r^2 +r -12

Factor

What number multiply to -12 and add to 1

4*-3 = -12

4-3 = 1

0= (r+4) (r-3)

Using the zero product property

r+4 =0 r-3 =0

r+4-4 =0-4 r-3+3=0+3

r = -4 r = -3

Assuming r is the radius, r must be positive

r =3

Three consecutive even integers are such that the square of the third is 76 more than the square of the second. Find the three i

Arada [10]

Let n represent the interger l, the three consective intergers are represented by

$n$

$n + 2$

$n + 4$

The second one represent

$(n + 2) {}^{2} + 76 =( n + 4) {}^{2}$

Simplify both sides

$n {}^{2} + 4n + 4 + 76 = {n}^{2} + 8n + 16$

${n}^{2} + 4n + 4 = {n}^{2} + 8n - 60$

$4n + 4 = 8n - 60$

$4n + 64= 8n$

$64= 4n$

$n = 16$

The intergers are 16,18,20
