Answer:
22.5
Step-by-step explanation:
a= √c2−b2
a=√676 - 169
a=√507
a=22.516660498395
AD = 6 - 2.4 = 3.6
AD/DE = AB/BC
3.6/DE = 6/10
DE = 3.6 x 10 / 6 = 36/6 = 6
answer
C. 6
A) 2.9
B) 2.0
C) 5.0
D) 0
E) 6.0
Answer:
The two circles centered at point A are concentric and similar.
Step-by-step explanation:
Height of the right circular cone = 18.8 metres
And base is 19.3 metres
Volume of the right circular cylinder is given by,
= πr²h
= 3.14 × (19.3)² × 18.8
= 21999.98(approx.) cubic metre
Rounding off nearest tenth
= 21999 cubic metres
