Explanation:

1) A=pi*r^2

A=pi*4^2

A=8pi

A=24.8

2) A=pi*t^2

A=pi*5^2

A=25pi

A=77.5

3) A=pi*r^2

A=pi*6^2

A=36pi

A=111.6

4) A=pi*r^2

A=pi*7^2

A=49pi

A=151.9

5) C=2*pi*r

81.64=3.14*2*r

26=r*2

r=13

A=pi*r^2

A=pi*13^2

A=169pi

A=523.9

6) C=2*pi*r

53.38=2*3.14*r

17=2*r

8.5=r

A=pi*r^2

A=pi*8.5^2

A=72.25*pi

A=223.975
