The sum of two circles is 80 pi square meters. find the length of a radius of each circle if one of them is twice as long as the other. what is the radiusof the larger circle?

the big circle has a radius of - 2r
the small circle has a radius of - r
never mind u guys didn't me in enough time i only got a 30% on my tes

Given:

sum of two circles is 80 pi square meters

big circle has a radius of - 2r
small circle has a radius of – r

Required:

r

Solution:

2r + r = 80 pi square meters

3r = 80 pi square meters

r = 26.67 pi meters

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
