A sector with a central angle measure of 175 has a radius of 12cm. What is the area of the sector

Answer»

A sector with a central angle measure of 175° has a radius of 12cm. The area of the sector is 220 cm²

Step-by-step explanation:

Central angle SUBTENDED by the arc at the centre θ = 175°

Radius of the CIRCLE r = 12 cm

We KNOW that area of sector is given by

\boxed{A=\frac{\theta}{360^\circ}\times\pi r^2}

Therefore, the area of the sector is

A=\frac{175}{360}\times \frac{22}{<klux>7</klux>}\times 12\times 12

\implies A=220 cm²

Hope this answer is helpful.

Write an activity to show that acids do not have acidic behaviour in the absence of water. (Class 10 CBSE)

Answer»

Answer:

A good example is if your lead dry ammonia gas over dry, anhydrous zinc chloride powder. Zinc chloride is a pretty good Lewis acid and ammonia is a Lewis BASE. You can see the white powder fluff up and become more voluminous. The reaction produces a while solid ammine. (No, not amine)

ZnCl2(s)+2NH3(g)→ZnCl2(NH3)2(s)

In this solid the central zinc atom is surrounded by two chlorine atoms and two nitrogen atoms in a (distorted) tetrahedral arrangement. The Zn<-N BONDS are dative bonds formed by the ammonia lone PAIR.

Another good example is the gas phase reaction between HCl and ammonia. Here the ammonia lone pair ATTACKS the proton rather than a zinc atom. (So the acid is also Brønsted acid, not just Lewis acid). The two gases produce solid salmiak, SEEN as a smoke:

HCl(g)+NH3(g) =NH4CI(s)

GIVEN:

{24 \times 5 (68 +65) \times {7 \div (65+90) \times 3(54 \div 76)}

To FIND:

VALUE =?

SOLUTION:

\Rightarrow {24 \times 5 (68 +65) \times {7 \div (65+90) \times 3(54 \div 76)}\\\\

\Rightarrow {24 \times 5 (68 +65) \times {(\frac{7}{65+90}) \times 3(\frac{54}{ 76})}\\\\

\Rightarrow {24 \times 5 (133) \times {(\frac{7}{155}) \times 3(\frac{54}{ 76})}\\\\

\Rightarrow {24 \times 655 \times {\frac{7}{155} \times 3\times \frac{54}{ 76}}\\\\

\Rightarrow {6 \times 131 \times {\frac{7}{31} \times 9}\\\\

At what rate will the simple interest on 20000 for 4 years will be equal to the simple interest on 30000 for 3 years at 10%​

Answer»

GIVEN

At what rate will the simple interest on 20000 for 4 years will be equal to the simple interest on 30000 for 3 years at 10%

SOLUTION

In first CASE

  • Principal = Rs.20000
  • Time = 4yrs
  • Rate = ?

In SECOND case

  • Principal = Rs.30000
  • Time = 3yrs
  • Rate = 10%

According to the given condition

The simple interest on 20000 for 4 years will be equal to the simple interest on 30000 for 3 years at 10%.

(★) Simple interest = P×R×T/100

→ 20000 × R × 4/100 = 30000 × 10 × 3/100

→ 200 ×R × 4 = 300 × 10 × 3

→ 800R = 9000

→ R = 9000/800

→ R = 90/8 = 11.25 %

Hence, the required rate is 11.25 %

THERE ARE A LOT OF WAYS FOR ANSWERING THIS QUESTION I WILL TELL 2 OF THEM:

This is easier but time CONSUMING in bigger questions…. lets take your question for instance: increase in first year = 5/100 * 800 [that says 5 percent of 800] = 40……[then we increase the value and find the 1 year increased student] = 800+40 = 840………[now again 5% of 840] = 5/100 * 840 = 42……. therefore students after 2 years = 800+40+42=840+42 = 882

this is known as COMPOUND INTEREST which has a formula of ………………. a=p*[1+r/100]^t(only when population increases)…where p = principal….r=rate……t=time……..as we are solving population question then p=population…….rate=rate of increase of population………a=amount of population in total after increase..….t=time……lets solve the problem now . a=800[1+5/100]^2=a=800[1+1/20]^2 =800*21/20*21/20=a=882
