35 POINT PLS HELP ME WITH THIS

Answer 1

$\huge{\pink{Answer::}}$

For first Question:-

Given:-

Circumference of circle = 56 cm

Find:-

Diameter of circle

Explanation:-

we know,

★ Circumference of circle = 2πr

where , π = 3.14

r = radius

➩ 56 = 2 × 3.14 × r

➩ r = 56 × /(2 × 3.14)

➩ r = 28/3.14

➩ r = 2800/314

➩ r = 8.92 cm

Hence:-

Diameter will be = 8.92 × 2 = 17.84 cm

For second Question:-

Given :-

Circumference of circle = 25.12 cm

Find:-

Radius of circle

Explanation:-

we know,

★ Circumference of circle = 2πr

➩ 25.12 = 2 × 3.14 × r

➩ r = 25.12/(2 × 3.14)

➩ r = 12.56/3.14

➩ r = 1256/314

➩ r = 3.99 cm

Hence:-

Radius of circle = 3.99 cm

Answer 2

Answer:

Step-by-step explanation:

3. Given

π = 3.14

D = 14cm

r = D/2

= 14/2

= 7cm

Circumference of circle = 2πr

=> 2 * 3.14 * 7

=> 43.96cm

4.

r = 2.1 inches = 5.334 cm

=> 2πr

=> 2 * 3.14 * 5.334

= 33.497 cm
