The sum of the areas of two circles is 80 square meters. Find the length of a radius of each circle if
one of them is twice as long as the other.

Step-by-step explanation:

let the radius of one circle be r and the other be R,

there fore,

2πr + 2πR = 80

=> 2π( r + R) = 80

but we know that, R =2r

=> 2 π ( 3r) = 80

=> 3r = 40/π

=> r = 40/3π

taking the value of pi to be 3.14

=> r = 40/9.42

=> r = 4.246

hence the larger radius = 2r => 8.492

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
