Answer:

49.12 square inches

Step-by-step explanation:

Area of a circle = Pi x r^2

= 3.14 x 4^2

= 3.14 x 16

= 50.24

Half the circle = 25.12 squared inches

Area of a triangle = base x height /2

= 6 x 8 /2

= 24

25.12 + 24 = 49.12 square inches

Mr. Hammond is the volunteer coordinator for a company that puts on running races. Last year, the company organized 7 short race

worty [1.4K]

Answer:

28 short race volunteers

76 long race volunteers

Step-by-step explanation:

Let :

Short races = a

Long races = b

LAST YEAR:

7a + 8b = 804 - - - - (1)

THIS YEAR:

11a + 5b = 688 - - - (2)

Multiply (1) by 5 and (2) by 8

35a + 40b = 4020

88a + 40b = 5504

Subtract

-53a = - 1484

a = 1484 / 53

a = 28

Put a = 28 in equation (1)

7(28) + 8b = 804

196 + 8b = 804

8b = 804 - 196

8b = 608

b = 76

28 short race volunteers

76 long race volunteers
