Answer:

B

Step-by-step explanation:

CIRCLE AREA= RADIUS TO THE SECOND POWER TIMES PI

Half circle= Radius to the second power times pi divided by two

Radius= half of diameter

Radius of the half circle in the problem is 4 cm.

4x4=16

3.14x16

50.24/2

25.12

TRIANGLE= 8x7= 56

56+25.12

81.12

The area of the figure is 81.12.

The calculation is as follows:

Since Radius= half of diameter

So,

Radius of the half circle in the problem is 4 cm.

[tex]4\times 4=16\\\\= 3.14\times 16\\\\= 50.24\div 2[/tex]

= 25.12

Now

TRIANGLE= [tex]8\times 7= 56[/tex]

= 56+25.12

= 81.12
