Answer:
D: 8,100π in²
Step-by-step explanation:
The formula for area of a circle is
A = πr²
The radius is squared, so if the radius or a new circle is 6 times larger (multiplied by 6), the difference in area will be 36 times greater. So the area is
225π(36) = 8,100π

Answer:
2.83
Step-by-step explanation:
85 divided by 30 = 2.83
.25 times 2.83 = .70 cents
So first we need to find what percent of the students walk to school.
50 + 35 = 85% don't walk leaving only 15% that walk to school,
To find the 15% percent that DO walk we multiply .15 by the total number of people.
.15 x 1640 = 246 people walk to school
