Question

what is the diameter of a circle whose circumference is 11 cm

Answer 1

Answer:

Step-by-step explanation:

Circumference = 2$\pi$r

11 = 2*22/7*r

r = 7/4

Diameter = 2r

d = 2*7/4

d = 7/2 = 3.5 cm

Answer 2

HEY MATE


HERE IS UR ANSWER



GIVEN:
______

CIRCUMFERENCE = 2 pi r = 11cm


CALCULATION:
_____________

to find radius....

r = 11 × 1 × 7 ÷ 22 × 2

r = 7/4

= 1.75 cm


so we know that diameter = 2r

2 × 7/4

= ● 7/2 cm or 3.5cm
