Answer:

r = sqrt(11)

Step-by-step explanation:

Area of sector, A = (theta) r^2/ 2 = 11 cm^2

Perimeter of sector, p= r theta+2r

Length of arc AB, a= r theta

We are given that p = 2a, so equate

r theta + 2r = 2(r theta)

2r = r( theta )

theta = 2 (radians)

Solve for r from area

Area = (theta) r^2 /2 = 11

substitute theta = 2

2 r^2 /2 =11

r^2  = 11

r = sqrt(11)

Alex has a box of pens and pencils. Of all his pens and pencils,
drek231 [11]

Answer:

a. p = n + m

where: n is the number of pens, and m is the number of pencils

b. p = 71

Step-by-step explanation:

Let the number of pens  and pencils that Alex has be represented by n and m respectively.

But,

number of pens, n = 14

number of pencils, m = 57

Then,

total number of pens and pencils, p = number of pens + number of pencils

i.e p = n + m

p = 14 + 57

p = 71

The total number of pens and pencils that Alex has is 71.
