Step-by-step explanation:
Important information:
Circumference of a circle= 
Method:
To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.
Step By Step:
1) Rearange the formula to make the diameter the subject.

2) Divide 34.54 by 3.14(
).

I don’t really understand what this is asking but the formula for circumference is C= πd Remember that diameter (width of the circle) is double the radius (half the width of the circle) and π is about 3.14

Answer:
6 vans
Step-by-step explanation:
If 1 van can seal 18 students...
116 ÷ 18 = 6.4
Since it's not a whole number, we will estimate it to the nearest whole number which is 6.
Sets of three integers that could be right triangles are called pythagorean triples. the only pythagorean triple including 7 is 7, 24, and 25. so the length of the other leg is 24 and the length of the hypotenuse is 25. hope this helped!
