To find<span> the perimeter of the </span>quarter circle<span>, </span>find<span> the circumference of the whole </span>circle<span>, divide by 4, and then add the radius twice. To </span>find<span> the radius when you are given the </span>area<span> of the </span>quarter circle<span>, multiply the given </span>area<span> by 4, then plug this number in for A into the formula A = pi * r^2 and then solve for r.</span>
Given that the crust formed is cylindrical with the height which is equal to the radius of the sphere, then the volume will be given by:
V=πr^2h
V=π*8^2*12
V=2,412.743 cm^3
We conclude that the volume of the crust is 2,412.743 cm^3
Answer:
B
Step-by-step explanation:
Answer:
0x+2y=22
Step-by-step explanation:
Set them equal to each other, (5x+4y=25)-(5x+2y=3). Distribute the negative into the right equation, (5x+4y=25)(-5x-2y=-3). Then combine like terms to get your answer.
