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

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
