In circle g, r = 3 units. maria draws a circle with double the area of circle g. what is the area of maria’s circle?

the area of maria's circle is

step-by-step explanation:

we know that

the area of a circle is equal to

where

r is the radius of the circle

find the area of circle g

substitute the value of r in the formula

find the area of maria's circle

let

> area of the circle g

> area of maria's circle

substitute

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

the correct answer is 1: 2
