Question

Maths written asignment solve properly pls​

Answer 1

Answer:

Hello...

Step-by-step explanation:

2. Circumference = 28 cm

2 × pi × r = 28 cm

r = 28/2 × pi

r = 14 × 7/22

r = 4.4545....

d = 2 × r

d = 8.9090909091

3. The ribbon should be 13 + 13 = 26 cm

Answer 2

Answer:

$= = > 2\pi \: r = 28$

$= = > 2 \times \frac{22}{7} \times r = 28$

$= = > r = 28 \times \frac{7}{44}$

$= = > 7 \times \frac{7}{11}$

$= = > r = \frac{49}{11}$

$diameter = 2r \\ so \: 2r = \frac{49}{11} \times 2$

$= = > \frac{98}{11}$

2) The ribbon would be tied on the perimeter. so perimeter of circle = 2πr

$= = > r = \frac{d}{2}$

$= = > r = \frac{13}{2}$

$p = 2 \times \frac{22}{7} \times \frac{13}{2}$

$p = \frac{22 \times 13}{7}$

$= = >p = \frac{286}{7}$
