Answer:

<h2>3.14159</h2>

Step-by-step explanation:

A) Pi value using circumferences

C = circumference

d= diameter

Formula: C = Pi*d⇒Pi = C/d

Circle A)

Pi = 21.98/7 = 3.14

Circle B)

Pi = 18.84/6= 3.14

B) Using areas

A = area

r = radio = diameter/2

Formula: A = Pi*(r^2 )⇒ Pi = A/(r^2)

Circle A

Pi = 38.465/(3.5)^2= 3.14

Circle B

Pi= 28.26/(3^2)= 3.14

Gre4nikov [31]

Answer:

335.5 in^2

Step-by-step explanation:

The area is a rectangle and a triangle

The area of the rectangle is

A = a*b where a is 11 and b is 25

A = 11*25 =275

The area of the triangle is

A = 1/2 b*h  where b is 11 and h is 11

A = 1/2 (11) * 11

A = 60.5

The total area is 275+60.5=335.5

There were 72 runners to start a race. in the first half of the race, 13 of them dropped out. in the second half of the race, 23
Mariana [72]
All you would need to to is do 13+23= 33 to get the total amount of people who dropped out, then do 72 ( the number in the beginning and subtract 33 from it because those are the people who dropped out so 72-33=39. 39 people finished the race.
