Answer:
Step-by-step explanation:
Need to find the value of t, when h(t) = 0
-
-16t^2 +64t + 100 = 0
- 4t^2 - 16t - 25 = 0
- 4t^2 - 2*2t*4 + 16 = 41
- (2t - 4)^2 = 41
- 2t - 4 = √41
- 2t - 4 = 6.4
- 2t = 10.4
- t = 5.2
Answer is 5.2 seconds
Answer:
- The surface area of Cylinder B is 16 times the surface area of Cylinder A
Step-by-step explanation:
<u>Note</u>: <em>It is assumed we are looking at the total surface area (but the answer would be same for both cases)</em>
<h3>Given</h3>
- Cylinders A with radius - r, height - h,
- Cylinder B with radius - 4r, height - 4h.
<h3>To find </h3>
- The ratio of total surface areas of cylinder B to A
<h3>Solution</h3>
Total surface area of cylinder A is:
Total surface area of cylinder B is:
Find the ratio of areas:
