2.

What a amount of milk that hemispherical bowl of radius 10 cm can hold.

Answer»

ong>ANSWER:

Given data

diameter =10.5 cm

Volume of the bowl which is HEMISPHERE =32πr2→(1)

where r→ radius

r=2d=210.5=5.25 cm→(2)

Substituting (2) in (1)

V=32×722×5.25×5.25×5.25

=303.1875 CM3(π=722)

The answer must be CONVERTED into lives as it was asked to be calculated in litre

V=303.1875×10001 litre

=0.3031875 litre

=0.303 litre (approx) [∴ 1 cm3=10001litre]

Hence, the hemispherical bowl can hold 0.303litre.

5.

A constant force acts on an object of mass 2kg for 10s and increases its velocity from 5m/s to 10m/s. Find the magnitude of force applied.

Answer» ONG>ANSWER:

Step-by-step explanation:

M=2kg=

t=10sec

u=5m/sec

v=10m/sec

v=u+at

a=(v-u)/t=(10-5)/10=1/2m/sec²

F=Ma=2×1/2=1kgm/sec²=1N

if this force is applied for 15sec then, VELOCITY is

F=mv/t

v=(1×15)/2=7.5m/sec.

9.	The breadth and height of room are 10 m and 4m.If the area of room is 168 m. Then find 1]Height 2] Cost of white washing at ₹10 per m 3] Area of floor
Answer» >Given :- Breadth of room = 10 m Height of room = 4 m Area of room = 168m To Find :- I]Height 2] Cost of white washing at ₹10 PER m 3] Area of floor Solution :- Concept - At first we need to find the length by the formula 2[L +b]×h. Then we will find the cost of white washing. By multiplying the Area by 10. After we will multiply length and breadth to GET area $\sf \implies 168 = 2(10 + l) 4$ $\sf \implies 168 = 8[10 + l]$ $\sf \implies \dfrac{168}{8} = 10 + l$ $\sf \implies 21 = 10+l$ $\sf \implies 21 -10=l$ $\sf \implies 11 = l$ Length is 11 m Cost of white washing = Area of 4 walls × Rate Cost = 168 × 10 Cost = ₹1680 Cost of whitewashing is ₹1680 Area of floor = Length × Breadth Area of floor = 11 × 10 Area = 110 m²

9.

The breadth and height of room are 10 m and 4m.If the area of room is 168 m. Then find 1]Height 2] Cost of white washing at ₹10 per m 3] Area of floor

Answer»

>Given :-

Breadth of room = 10 m

Height of room = 4 m

Area of room = 168m

To Find :-

I]Height

2] Cost of white washing at ₹10 PER m

3] Area of floor

Solution :-

Concept - At first we need to find the length by the formula 2[L +b]×h. Then we will find the cost of white washing. By multiplying the Area by 10. After we will multiply length and breadth to GET area

$\sf \implies 168 = 2(10 + l) 4$

$\sf \implies 168 = 8[10 + l]$

$\sf \implies \dfrac{168}{8} = 10 + l$

$\sf \implies 21 = 10+l$

$\sf \implies 21 -10=l$

$\sf \implies 11 = l$

Length is 11 m

Cost of white washing = Area of 4 walls × Rate

Cost = 168 × 10

Cost = ₹1680

Cost of whitewashing is ₹1680

Area of floor = Length × Breadth

Area of floor = 11 × 10

Area = 110 m²

$\implies$ Here, the question has given us the SIDE of a square that is 8 cm respectively. Now, the question has asked us to find out the area of the given square. So, to find out its area we simply need to apply the formula of area of a square and we will EASILY get the answer.

ANSWER:-

✰ Area of the square is = 64 cm²

GIVEN:-

◐ Side of the square = 8 cm

TO FIND:-

⚩ Area of the square = ?

FORMULA:-

➙ Area of square = S × S

Where,

S = Side

SOLVING BY APPLYING THE FORMULA:-

◐ Side of the square = 8 cm

➙ Area of square = S × S

Finding the area:-

➜ Area = 8 cm × 8 cm

➜ Area = 8 cm × 8 cm = 64 cm²

➜ Area = 64 cm²

Thus, we got the answer. The area of the square is 64 cm².
