Answer:
Radius = 2.31 cm
Step-by-step explanation:
Area of circle = 16.71 square centimeters
Radius of circle = 2.31 centimeter
Let
v-------> <span> the volume of a sphere
s-------> t</span><span>he surface area of the sphere
r------> </span><span>the radius of the sphere
we know that
v=(4/3)*pi*r</span>³-----> v=(r/3)*4*pi*r²------> equation 1
and
S=4*pi*r²-----> equation 2
substitute equation 2 in equation 1
so
v=(r/3)*4*pi*r²-------> v=(r/3)*s
the answer is
the equation that <span>represents the relationship between these three measures
</span> v=(r/3)*s

Answer:
Choice two
Step-by-step explanation:
Quincy must calculate the pool’s volume in cubic feet, for each choice.
The volume is the product of the length, width and depth.
Volume = length x width x depth
Choice One: 5 ft. × 5 ft. × 1 ft. = 25 cubic feet
Choice Two: 4 ft. × 3 ft. × 1 ft. = 12 cubic feet
Choice Three: 4 ft. × 2 ft. × 2 ft. = 16 cubic feet

<u>Which of these choices is best for the baby pool?</u>
The best choice for the baby pool is number two, because this one requires less than 15 cubic feet of water.
<u>Why are the others not good choices?</u>
Because choice one and choice three are more than 15 cubic feet water, and won´t meet budget requirement.
The second choices is the correct answer
I hope that helped
