Question

Find the area. use 3.14 for pie... i will post picture

Answer 1

A=πr2

Answer 2

r = 1/2d
d = 10

Answer 3

Do you understand?

Answer 4

not really what would be next

Answer 5

Solve for r when d = 10
r = 1/2 * d

Answer 6

so are you just doing 1/2 * 10

Answer 7

For now, to solve for r.
r is the radius, d is the diameter. the radius is half of the diameter.

Answer 8

so if the radius is half the diameter thats 5

Answer 9

yeah, so solve for A when r = 5 and pi = 3.14
A=πr2

Answer 10

r2 = r^2

Answer 11

314

Answer 12

Not quite.
A = 3.14 * 5^2

Answer 13

78.5

Answer 14

Correct. :D
