Need help with assignment

1. r = 5 cm; area =  78.5 sq. cm.

2. diameter, d = 17';  area =  226.98 sq. ft.

3. diameter, d = 11"; area =  95.0 sq. in

4. radius, r = 2.4 m; area =  18.1 sq. m

5. radius, r = 30'; area =  2827.4 sq. m

Step-by-step explanation:

Area = pi * r^2

pi = 3.1416

1. radius, r = 5 cm

area = pi*5^2 = 78.5 sq. cm.

2. diameter, d = 17'

radius, r = d/2 = 8.5'

area = pi * 8.5^2 = 226.98 sq. ft.

3. diameter, d = 11"

radius, r = 11/2 = 5.5"

area = pi * 5.5^2 = 95.0 sq. in

4. radius, r = 2.4 m

area = pi * 2.4^2

= 18.1 sq. m

5. radius, r = 30'

area = pi 30^2

= 2827.4 sq. m

me i beg !
