Question

READ CAREFULLY! :)


John is putting a fence around his garden that is shaped like a half circle and a rectangle

Answer 1

Answer:

46 feet

Step-by-step explanation:

Perimeter of rectangle needed =

$14+14+7= 35$

Half of the circumference of a circle needed =

$\frac{1}{2} \pi d = \frac{1}{2} * \frac{22}{7} * 7= 11$

Total perimeter needed =

$35 + 11=46$

Answer 2

Answer:

46 ft

Step-by-step explanation:

John will need to put a fence along 3 sides of the rectangle: 14 ft, 7 ft, 14 ft

He also needs to put a fence along the half circle:

C (circumference) = 2×π×r = π×d

⇒C÷2 = π×d÷2 = 22/7×7÷2 = 22÷2 = 11 ft

Together: 14 + 7 + 14 + 11 = 46 ft
