The parallel sides of a trapezium are 10 cm and 22 cm. Its non parallel sides are 10 cm each then the area of the trapezium is

Solution:

In Δ CEB CE = 10 cm, CB = 10 cm, EP + PB = EB = 12 cm
In Δ CEP CE = 10 cm, EP = 6 cm
CP2 = 102 - 62
CP = 8
Here h = 8 cm
Area of trapezium is = 1/2 (sum of parallel side) (height)
= 1/2 (10 + 22) (8)
= 1/2 (32) (8)
= 128 cm2

QUESTION: 121

Solution:

Area of the park minus the paths
= (200 - 3) (150 - 2)
= 197 x 147 sq. m

QUESTION: 122

If 47.2506 = 4A+( 7 B )+2C+( 5 D )+6E, then the value of 5A+3B+6C+D+3E is :

Solution:

Given 47.2506 = 4A + 7 B + 2C + 5 D + 6E .....(i)
Now, write 47.2506 = 40 + 7 + 0 2 + 0.05 + 0.0006 .....(ii)
Comparing (i) and (ii), we get,
4A = 40 ⇒ A = 10
7 B = 7 ⇒ B = 7 7 ⇒ B = 1
2C = 0.2 ⇒ C = 0.1
5 D = 0.05 ⇒ D = 5 0.05 ⇒ D = 100
6E = 0.0006
⇒ E = 0.0001 ∴ The Value of 5A + 3B + 6C + D + 3E
= (5x 10) + (3 x 1) + (6 x 0.1) + 100 + (3 x 0.0001)
= 50 + 3 + 0.6 + 100 + 0.0003

QUESTION: 144

The radii of internal and external surfaces of a hollow spherical shell are 3cm and 5cm respectively. If it is melted and recaste into a solid cylinder of diameter 14 cm, the height of the cylinder is nearly

Solution:

Let Internal surfaces of a hollow spherical shell = r = 3cm
External surfaces of a hollow spherical shell = R = 5cm
Volume of hollow spherical shell = 4 3 π (R3 - r3)
Let the height of solid cylinder = h
Radius of solid cylinder = R1 = 14 2 = 7cm
Volume of solid cylinder = π R12 h
Now volume of hollow spherical shell = Volume of solid cylinder
⇒ 4 3 π (R3 - r3) = π R12 h
⇒ 4 3 ((5)3 - (3)3) = (7)2 h
⇒ 49 h = 392 3
⇒ h = 2.6666 ≅ 2.67
