Consider a circle that has a circumference of 28π centimeters.

PART A
What is the area, in cm^2, of this circle?

Part B
What would be the measure of the radius, in cm, of a circle with an area 20% greater than the circle in Part A?

dude thats to long figure it

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

the area of ​​the surface of the rectangular prism here is 250 cm2, which is the surface of the shading
