Answer: 9cm
Step-by-step explanation:
The circumference of a circle is given as: = 2πr
where,
π = 3.142
r = radius = unknown
Since circumference = 56.52cm, we'll slot it into the formula which will be:
Circumference = 2πr
2πr = 56.52
2 × 3.142 × r = 56.52
6.284r = 56.52
r = 56.52 / 6.284
r = 8.99
r = 9cm approximately
Plug the given x and y values (x, y) into the equations and solve
It look like the second equation is the answer.
Answer:

Step-by-step explanation:
Using pythagoras theorem,

Sector area= theta/360 x πr^2
Radius= 24/2= 12
Sector area= 120/360 x π(12)^2
Final answer :
Sector area = 48π
Answer:
3/4
Step-by-step explanation:
1/2/2/3= 1/2*3/2 which is 3/4
