Circle O has a circumference of 88π cm.
Circle O has a radius length of r.

The radius r of the circle is 44cm

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, a circular shape.

Given data

Circumference of circle C= 88πcm

Radius of circle r=?

The problem seeks to solve for the radius r.

To solve for the radius let us apply the formula for the circumference of a circle

C=2πr

Substituting our given data

88π=2πr

Making r subject of formula we have

r= 88π/2π

r= 44cm

r = 44 cm

Step-by-step explanation:

A circle has a circumference of 88π cm . The circumference of a circle is the distance around a circle. The radius can be calculated as follows.

circumference = 2πr

where

r = radius

circumference = 88π

circumference = 2π × r

88π = 2πr

divide both sides by 2π

r = 88π/2π

r = 44 cm

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
