A sector with an area of 140 pie cm^2 has a radius of 20 cm. r = 20 cm
A = 140 pie cm^2
What is the central angle measure of the sector in degrees?

Central angle = 126°

Step-by-step explanation:

Area of the sector = 140π cm²

Radius of the given circle = 20 cm

Since area of the sector =

[where θ is the central angle formed by the sector at the center]

                               140π =

                                    θ =

                                    θ = 126°

Therefore, central angle of the sector will be 126°.

(c, 0) i might be wrong so don't put full faith on my answer

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
