17.

Perimeter of rectangle is 15 3/7 . if the length is 4 2/7 .find its breadth

Answer»

Perimeter = 15 3/7 units (Given)

Length = 4 2/7 (Given)

Find the BREADTH:

Perimeter = 2 ( Length + Breadth)

Substitute Perimeter = 15 3/7 and Length = 4 2/7 :

15 3/7 = 2 (4 2/7 + Breadth)

WRITE as IMPROPER FRACTION:

108/7 = 2( 30/7 + Breadth)

Distribute 2:

108/7 = 60/7 + 2Breadth

Subtract 60/7 from both SIDES:

2Breadth = 108/7 - 60/7

2Breadth = 48/7

Divide both sides by 2:

Breadth = 48/7 ÷ 2

Breadth = 24/7

Change to improper fraction:

Breadth = 3 3/7 units

Answer: Breadth = 3 3/7 units

43.	A toy is in the shape of a cone mounted on a hemisphere of same base radius if the volume of the toyis 231cm ans its diameyer is 7cm find the height of the toy
Answer» Answer: 14.5003 cm Step-by-step EXPLANATION: Let the HEIGHT of cone be H Diameter of cone = 7 cm Radius of cone = $\frac{7}{2}=3.5 cm$ Volume of cone = $\frac{1}{3} \pi r^2 h$ = $\frac{1}{3} \times \frac{22}{7} \times 3.5^2 h$ = $12.833h$ Radius of HEMISPHERE = 3.5 cm Volume of hemisphere = $\frac{2}{3} \pi r^3$ = $\frac{2}{3} \times \frac{22}{7} \times 3.5^3$ = $89.833$ TOTAL volume of toy = 12.833h + 89.833 We are given that the volume of the toy is 231 cm . $12.833h + 89.833 = 231$ $12.833h = 231-89.833$ $12.833h = 141.167$ $h = \frac{141.167}{12.833}$ $h =11.0003$ Height of toy = 11.0003 + 3.5 = 14.5003 Hence the height of the toy is 14.5003 cm

43.

A toy is in the shape of a cone mounted on a hemisphere of same base radius if the volume of the toyis 231cm ans its diameyer is 7cm find the height of the toy

Answer»

Answer:

14.5003 cm

Step-by-step EXPLANATION:

Let the HEIGHT of cone be H

Diameter of cone = 7 cm

Radius of cone = $\frac{7}{2}=3.5 cm$

Volume of cone = $\frac{1}{3} \pi r^2 h$

= $\frac{1}{3} \times \frac{22}{7} \times 3.5^2 h$

= $12.833h$

Radius of HEMISPHERE = 3.5 cm

Volume of hemisphere = $\frac{2}{3} \pi r^3$

= $\frac{2}{3} \times \frac{22}{7} \times 3.5^3$

= $89.833$

TOTAL volume of toy = 12.833h + 89.833

We are given that the volume of the toy is 231 cm .

$12.833h + 89.833 = 231$

$12.833h = 231-89.833$

$12.833h = 141.167$

$h = \frac{141.167}{12.833}$

$h =11.0003$

Height of toy = 11.0003 + 3.5 = 14.5003

Hence the height of the toy is 14.5003 cm
