Answer:
8x
Step-by-step explanation:
x stands for a number
Answer:
Step-by-step explanation:
A) either radius or diameter and height
V = πR²h or πD²h/4
B) Radius is half a diameter, R = 4 cm
C) Rather depends on how they are put together.
Placing the rectangular faces touching would make a cylinder
D) V = 3.14(4²)(2) = 100.48 ≈ 100 cm³
E) divide by 2
i.e. V = ½πR²h
F V = ½(3.14)(4²)(2) = 50.24 ≈ 50 cm³
Reason:
2. SD ⊥ HT. ∴ ∠SDH = ∠SDT =90°
3. Given (It is given in the question)
5. RHS congruence
(Here, the right angle, hypotenuse and one side of ΔSHD is congruent to that of ΔSTD).
Statement:
4. Line segment SD = SD
(Reflexive property is used to prove congruence of triangles. This property is used when an angle or line segment is congruent to itself.)
