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

The correct answer is B. 880
220%=2.2
2.2(400)=880
42 is the right answer
15 m ^2
3 x 10 is 30
divide that by 2 since the triangle can fit in half of the rectangle shape
you will get 15
