Answer:
51.89085
Step-by-step explanation:
area = 49pi
150/360 * 49pi = 64.14085
triangle area = 7 * sin(75 degrees) * 7 * cos(75 degrees) = 12.25
==> white region = 64.14085 - 12.25 = 51.89085
Another way is to put it in word form
Answer:
x=1
Step-by-step explanation:
(15x^3- 2)^3= 2197
Take the cube root of each side
(15x^3- 2)^3 ^ 1/3= 2197^ 1/3
15x -2 = 13
Add 2 to each side
15x^3- 2+2= 13+2
15x^3 =15
Divide each side by 15
15x^3 /15 =15/15
x^3 =1
Take the cube root of each side
x^3 ^1/3 = 1^1/3
x=1
