Answer 1

2) 1.77 in squared

3) 508.68 in squared

4) 50.24 ft squared

5) 562.6

6) 170.3

Explanation:

2) A=r^2pi

d= 2r

3in= 2r

r= 3/2

(3/2)^2pi

7.06858/4

1.77 in^2

3) (18)^2pi

324(pi)

1017.876/2

508

4) (8)^2pi

64pi

201.062/4

50

5) A= 1/2(b1+b2)h

25 -4.2= 20.8

1/2(18+26)20.8

1/2(44)(20.8)

22(20.8)

457.6cm^2

A=lw

25(4.2)

105cm^2

105+457.6= 562.6

6) 2 triangles(1/2(6.2(5)))

31 m^2

18.3(11)

201.3m^2

201.3 -31= 170.3m^2
