Answer: the first picture is 36 cm^2.
Step-by-step explanation:
It's 36 cm^2 because you need to multiply the length and breadth which is 12*3= 36. Hope this helped !
Answer:
Step-by-step explanation:
What we're looking for here is the volume of this ball, which is the volume of a sphere:

If our diameter is 3, then the radius is 1.5:

In terms of π, the solution is
which can also be expressed as 
Or if you have to multiply in the pi, the solution is
V = 14.14 cubic inches
Hey there,
For the first one, your answer will be C. The height of the plant increases by 2 mm for every hour of sunlight it receives. For the second one, It is B.<span>There is a strong negative relationship between x and y. And the last one is B. </span><span> It is greater for Group B than Group A.
I hope I helped :)</span>
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.
The greatest common factor is 1
