$\huge\tt{GIVEN:}$

Reema wants to enclose a circular garden with a fence.

Diameter = 5 ft.

____________________

$\huge\tt{TO~FIND:}$

the minimum fencing she must buy or the circumference of the circle

____________________

$\huge\tt{FORMULAS~USED:}$

The circumference of circle= 2πr

Finding radius = D/2

____________________

$\huge\tt{SOLUTION:}$

We can say that, The circumference of the circular garden = The fencing she have to buy

____________________

First, let's find the radius

Radius = D/2

↪ 5/2

↪2.5 ft.

____________________

As we know,

Circumference = 2πr

↪2× 3.14×2.5

↪5×3.14

↪15.7 ft.

Now in question,we are asked to round off the answer, then if we round off 15.7 ft., we'll get 16 feet as the answer.

Answer 2

✰✰|| Given ||✰✰

• Diameter of garden = 5ft

✰✰|| To Find ||✰✰

• minimum length of fencing after estimating

✪|| Solution ||✪

diameter = 2 × radius

→ 5 ft = 2 × radius

→ radius = 5 ft/2

→ radius = 2.5 ft

length of fencing = circumference of garden.

Circumference of garden = 2πr

= 2 × 22/7 × r

= 44/7 × 2.5ft

= 110/7 ft

= 15.7 ft

Length of fencing is 15.7 ft

Length of fencing after rouding = 16ft

Length of fencing Reem is 16 ft
