To prove that the perpendicular from the centre to a chord bisect the chord. Consider a circle with centre at O and AB is a chord such that OXperpendicular to AB To prove that AX=BX In ΔOAX and ΔOBX ∠OXA=∠OXB [both are 90 ] OA=OB (Both are radius of circle ) OX=OX (common side ) ΔOAX≅ΔOBX AX=BX (by property of congruent triangles ) hence proved.

Prove that the line drawn through the center of a circle to bisect a chord is perpendicular to the chord.

Given :-

O is the center of circle
AB is chord of circle
OX bisects AB i.e. AX = BX

To Prove :-

OX ⊥ AB

Explanation :-

➠ In ∆AOX and ∆BOX,

➠ On line AB,

Hence, ∠AXO and ∠BXO form a linear pair

Hence, Proved.

First take LCM of all Fractions 8,12,7,12,16 That will be 2×2×2×2×2×7=16×14 =224 Then see that 224 comes on which number in each of denominator(i.e. 8,12,7,12,16). Then multiply the number on which 224 comes in denominator by numerator. Then add all and at last simplify it and hence, your answer comes.

Since, The volume of a cylinder is,

Where r is the radius of the cylinder and h is the height.

Here, the diameter of one cylinder = 7 cm,

⇒ Radius of one cylinder, r = 7/2 = 3.5 cm

And, the height of a cylinder, h = 11 cm,

⇒ The volume of 1 cylinder,

⇒ The volume of 50 cylinder = 50 × 423.115

Gaurav Seth 3 years, 9 months ago

Slant height of the conical cup, 'l' = radius of the semi-circular sheet, R = 14 cm
Let radius and height of the conical cup be 'r' and 'h' respectively.
Circumference of the base of the cone = Length of arc of the semi-circle
Or, 2πr = (1/2)2πR
Or, 2πr = (1/2)(2π)(14)
Or, r = 7 cm
Now, we know that l² = h² + r²
(14)² = (h)² + (7)²
h² = 196 - 49
h = √147
Height or depth of the conical cup = 12.124 cm
Now, capacity of the conical cup = 1/3πr²h
= 1/3*22/7*7*7*12.124
= 13069.672/21
Capacity of the conical cup = 622.365 cu cm
