Question

Help anyone can help me do this question,I will mark brainlest.​

Answer 1

Step-by-step explanation:

GIVEN =

d= 49cm

$\pi = \frac{22}{7}$

To find = Circumference of a circle

SOLUTION =

CIRCUMFERENCE OF THE CIRCLE = πd

$\frac{22}{7} \times 49$

= 22 × 7

154cm

the circumference of the given circle is 154cm

Answer 2

Answer:

Step-by-step explanation:

5) diameter = d = 49 cm

Circumference = πd

                         $= \frac{22}{7}*49\\\\= 22 *7\\\\= 154 \ cm$

6) d = 20 mm

Circumference = π* 20

                         = 20π mm
