The diameter of a circular park is 56 m. On its outside, there is 3 m wide path, running around it. findcost of turfing the path at 5 per square metre.​

Answer»

Diameter of CIRCLE=56m.

RADIUS of circle= diameter/2.

R=56/2.

R= 28

Around PATH of 3m.

Full radius of circle=28+3=31.

Volume of circle=2πr.

V.of.circle=2×22/7×31

Answer»

Answer:

50 Rs/m

Step-by-step explanation:

As per given INFORMATION, the association MEMBERS paid a total of 55000 for installation of fence on all six sides of the PARK.

Lengths of all six sides are;

Side 1 fence = 150 m

Side 2 fence = 100 m

Side 3 fence = 120 m

Side 4 fence = 280 m

Side 5 fence = 180 m

Side 6 fence = 270 m

Total length of fence = 150 + 100 + 120 + 280 + 180 + 270

Total length of fence = 1100 m

Cost of fence / m = 55000 / 1100

Cost of fence / m = 50 Rs/m

If Rs.600 amounts to Rs.1510 at compound interest in 12 years. Find the rate of compound interest?​

Answer»

RATE of compound interest = 8%

Step-by-step EXPLANATION :

Given that,

principal (P) = Rs. 600,

amount (A) = Rs. 1510 and

TIME (t) = 12 years

We have to find, compound rate of interest R

Now, A = P (1 + r/100)ᵗ

or, 1510 = 600 * (1 + r/100)¹²

or, (1 + r/100)¹² = 151/60

or, 12 * LOG(1 + r/100) = log(151/60)

or, log(1 + r/100) = 1/12 * log(151/60)

or, 1 + r/100 = 10^0.0334

or, r/100 = 1.08 - 1

or, r = 100 * 0.08

or, r ≈ 8

required rate of compound interest is 8%

Draw triangle POR where the angles are in ratio 1:2:3 Draw triangle ABC similar to triangle PQR whose sides are 1/3 times the side of Triangle PQR​

Answer»

Answer:

Let each SIDE of the equilateral triangle be a.

As shown in the above image, consider the perpendicular distances as

OS = x

OU = y

OT = z

AREA of the equilateral triangle PQR = √3a243a24 ------------(1)

 

Area of triangle POQ = 1212 × PQ × OS = ax2ax2 ------------(2)

Area of triangle POR = 1212 × PR × OU = ay2ay2 ------------(3)

Area of triangle QOR = 1212 × QR × OT = az2az2 ------------(4)

Area of triangle PQR = (Area of triangle POQ + Area of triangle POR + Area of triangle QOR)

√3a24=ax2+ay2+az23a24=ax2+ay2+az2

√3a4=x2+y2+z23a4=x2+y2+z2

√3a4=x+y+z23a4=x+y+z2 

a = 2√3(x+y+z)23(x+y+z) ---- (A) . This can be used as a general formula for such questions.

Applying the given values, 

a =2√3(x+y+z)=2√3(√3+2√3+5√3)=2(1+2+5)23(x+y+z)=23(3+23+53)=2(1+2+5)= 16 cm

The diameter of a circular park is 56 m On its outside, there is 3 m wide path running around it .findcost of turfing the path at 5 per souare metre.it into the shape of a circle. Find the radius​

Answer»

Step-by-step explanation:

Given The diameter of a circular park is 56 m On its OUTSIDE, there is 3 m wide path running AROUND it .find  cost of turfing the path at 5 per SQUARE METRE. it into the shape of a circle. Find the radius​

  • cost of turfing the path at 5 per square metre.
  • it into the shape of a circle. Find the radius
  • The diameter of a circular park = 56 m
  • Radius of a circular park r = 56 / 2 = 28 m
  • Width of path = 4 m
  • Radius of the park with path R = 28 + 4 = 32 m
  • Area of path = Area of outer circle – Area of the inner circle
  •                    = πR^2 – πr^2
  •                     = π (R^2 – r^2)
  •                     = π (R + r) (R – r)
  •                    = 22/7 (32 + 28) (32 – 28)
  •                   = 22/7 x 60 x 4
  •                  = 754.2 m^2
  • Now the cost of turfing the path of 1 m^2 = Rs 5
  • Therefore cost of turfing the path of 754.2 m^2 is Rs 5 x 754.2
  •                                                                                = Rs 3771.42
