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:
Answer:
x = 7
Step-by-step explanation:
BD is an angle bisector of ∠ABC,
Therefore, by angle bisector theorem,
∠ABD ≅ ∠CBD
m∠ABD = m∠CBD
(2x + y) = (14 + y)
2x = 14
x = 7
Answer:
X = 75
Step-by-step explanation:
here, DY || FS ,
SO, Angle DFS = Angle JDY
( Corresponding angle pair )
Angle JSF = Angle JYD
( Corresponding angle pair )
Hence, triangle JDY ~ JFS ( By AA CRITERIA )
Now, JY / YS = JD / DF
=》42 / 63 = 50 / X
=》X = 50/42 × 63
=》X = 75
i hope you got it
