find the diameter of a circle whose circumference is 66m
rajju3:
2 pi d=66, 2×22\7d=66, d=66×7\2×22, d=10.5
As I don't have opt in my keyboard as pi symbol
correct ans will be 66÷ 3.14
66=22/7d and the answer is 21
Diameter is 33
how can you explain
No diameter is the 10.5
no the correct answer is 21

given 2πr=66
2×22/7×r=66
r=33×7/22
r=21/2
we know that diameter = 2r
therefore diameter is 21cm.
if u like the ans mark it as brainliest answer
2×22/7×r=66
r=33×7/22
r=21/2
we know that diameter = 2r
therefore diameter is 21cm.
if u like the ans mark it as brainliest answer
thank i
sry thank u
welcome
But we can use that method also to find diameter
66÷3.14
oh I see
The unit is metre(m) not centimeter(cm)
Change it plzz
The unit is wrong

r=66
2r= 66* 7/22
2r= 3*7
2r = 21m
Since diameter is equal to twice of radius therefore the diameter is 21m
2r= 66* 7/22
2r= 3*7
2r = 21m
Since diameter is equal to twice of radius therefore the diameter is 21m
thanx varun
