Answer:
Q10 is 13.64 cm3
Q 11 is 221 cm3
Step-by-step explanation:
volume is cross sectional area times height for Q 10
volume is length times width times height for Q 11
Answer:
Step-by-step explanation:
area of circle = πr² = 25π ft²
area of sector = 25π × 221°/360° ≅ 48.21 ft²
(n-2) × 180<span>° = 4 x 180 = 720
so sum of interior angles = 720
x = 720 - (112+133+128+ 100+120)
x = 720 - 593
x = 127
answer
x = 127</span>
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar
(a)
The corresponding angles are congruent , that is
∠ A = ∠ D , ∠ B = ∠ E , ∠ C = ∠ F
(b)
The ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
24 ? = 168 ( divide both sides by 24 )
? = 7
