Answer:
When there are numbers like that next to the radical it means multiply. like this: 2<u>√9</u>. You would first figure out the square root. <u>Square root of 9</u> is 3. 2 times 3 is 6.
After you figure out those problems, you just need to put the number, x, and y in an equation with 2 unknowns.
Step-by-step explanation:
So the formula for a circle is Pie * r^2
If you divide 300 by pie and then Square root it you would get your radius
And once you have the radius you would use the equation of 2pie * r to find the circumfrence.

Answer:
The speed of the boat is 20 km/hr
Step-by-step explanation:
Let s be the speed of boat in still water
Let d be the distance
Upstream speed = s-4
Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.
So, Distance traveled in upstream =
Downstream speed = s+4
So, Distance traveled in downstream = 
So, 
30s-120=20s+80
10s=200
s=20
Hence The speed of the boat is 20 km/hr
Answer:
