Question

Use 3.14 to approximate pi the options are

a) 32
b) 49.12
c) 36.56
d)25.12
e) 41.12
f ) 10.21

Answer 1

E

Explanation:

This figure contains a square and a quarter of a circle

The perimeter is the sum of all side lengths

Let's find the circumference of the quarter of a circle:

`0.25c = 2\pi * r`

The diameter is equal to a square's side length:

d = 8

hence, r = 0,5 × 8 = 4

`0.25c = 2 * 3.14 * 4 = 25.12`

Now, we can find the perimeter:

P = 25,12 + 8 + 8 = 41,12
