Find the area of sector of Circle of radius 5m.if the corresponding arc of length is 3.5m?

Question

Answer

Q/360*2πr=3.5mcalculate the angleQ from it and put Q/360*πr*r

Answer

Area of sector =1/2 x l x r=1/2 x 3.5 x 5=8.75 m²this is also a formula for finding area of sector if arc length is given.......... (l=arc length) No!! my answer is not from Google...... we were already had been taught this formula......

Answer

Raunak, we r telling you :another formula to find area of sector = 1/2 x arc x r. Again y ur taking theta/360x pie r formula.

Answer

Please tell me that this formula is not in ncert so how can we use it in board exam

Answer

Given radius(r) = 5cmarc length(l)=3.5cmWe know, l=r(x) {where x is angle subtended by sector} So, 3.5=5(x)x=0.7Area of sector=(x/360) x (area of circle with corresponding radius) =(0.7/360)x(3.14 x 25)=Calculate urself.

Answer

Yes , is is a formula ....the formula is given in both R.D. Sharma as well as R.S. Agarwal

Answer

Because I have seen the answer in brainlyI am telling you manojnot #anjali.The first answer you gave was from brainly.Ok

Answer

Friend I want to know that is it in ncert or not

Answer

Ye 1/2×l×r formula kahan se aaya.formula to theta by 360 into 2pi r hota hai.plz accept chat request so I may discuss the problem

Answer

Abey viraj, the answer given by anjali is correct, it is also from Google.

Answer

Copied from brainly

Answer

Friend the problem is that answer is not coming by formula theta by 360 degree into 2pi r equal to 3.5 .then using theta by 360 degree into pi r square

Answer

Understanding the Sector of a Circle
A sector of a circle is a portion of the circle enclosed by two radii and the arc between them. To find the area of a sector when the radius and arc length are known, we can use the relationship between arc length, radius, and angle in radians.
Given Information
- Radius (r) = 5 m
- Arc Length (L) = 3.5 m
Finding the Angle in Radians
To find the angle (θ) in radians, we use the formula:
- θ = L / r
Substituting the values:
- θ = 3.5 m / 5 m = 0.7 radians
Calculating the Area of the Sector
The area (A) of a sector can be calculated using the formula:
- A = (1/2) * r² * θ
Now, substituting the values:
- A = (1/2) * (5 m)² * 0.7
- A = (1/2) * 25 m² * 0.7
- A = 12.5 m² * 0.7
- A = 8.75 m²
Final Area of the Sector
Thus, the area of the sector of the circle is:
- Area = 8.75 square meters
This area represents the space enclosed by the two radii and the arc of length 3.5 meters in a circle with a radius of 5 meters.
