Answer: 889.66
Step-by-step explanation:
Volume of sphere is 4/3 \pi r3 and cylinder is \pi r2 h,
r=5
h=8
volume of sphere is 4/3 x 3.14 x 5x5x5 / 2 (since half of sphere) = 261.66
volume of cylinder is 3.14 x 5x5 x 8 = 628
total volume = 261.66+628 = 889.66
Answer:
(A)Z(-3,-7)
Explanation:
The rotation of a point (x,y) by 180 degrees gives the point (-x,-y).
That is:
![\text{Rotation by }180^0=(x,y)\rightarrow(-x,-y)](https://tex.z-dn.net/?f=%5Ctext%7BRotation%20by%20%7D180%5E0%3D%28x%2Cy%29%5Crightarrow%28-x%2C-y%29)
If the image point after rotation is (3,7), the coordinates of the pre-image will be:
![(x,y)=Z(-3,-7)](https://tex.z-dn.net/?f=%28x%2Cy%29%3DZ%28-3%2C-7%29)
The correct option is A.
