I guess it's the first dia. which is not intersecting....
Answer:
Since this is old, im just gonna get these points, don't wan't them to go to waste lm.ao
Step-by-step explanation:
The circle was 126 meters around.
Step-by-step explanation:
Step 1; It is given that the big circle was 40 feet across the center. This implies the distance from any particular point on the circle to any other point is 40 feet. This means the diameter of this given circle is 40 feet. Any given circle's radius is 0.5 times the diameter of that same circle. So we divide 40 by 2 to get the circle's radius. So the radius is 40/2=20 feet. So the radius of this given circle is 20 feet.
Step 2; To find how many feet around means we need to find perimeter and not area. Area means the region inside the circle whereas perimeter is how long the circle is i.e how long the circle around is. So the distance around this circle is 2 multiplied with pi and its radius. The distance around any given circle = 2πr.
Perimeter of this circle = 2 × 3.141592 × 20 = 125.6637 feet.
Divide.
3/4 / 1/12
Flip the 2nd fraction and multiply:
3/4 * 12/1
Multiply the numerators and denominators together:
36/4
Divide:
9
So the bee made 9 trips.
Answer:
The area of the circle is 28.26.
Step-by-step explanation:
πr =9.42
Using that, we can find the radius, which will help us find the area of the circle.
9.42/π = 3 (I used 3.14 for π)
The formula for area of a circle is:
πr^2
Plug our values in.
π(3^2)
9π
28.26
The area of the circle is 28.26.
To sum, Min would need to first figure out the radius of the circle, and then use the radius to find the area of the circle. She can figure out the radius by dividing 9.42 by π, and find the area with the formula πr^2.
