Question

Saima wants to put a lace on the edge of a Circular table of Diameter 1.5 m. Find the length of the lace required and also find its cost if one meter of the lace costs ₹ 15. ( Take π = 3.14 )​

Answer 1

Answer:

solution:-

☞circumference =πd=1.5πm

length of lace required = circumference of circle

=1.5×3.14=4.71m

length of lace required =4.71m

one meter of lace =Rs.15

4.71m lace =is finded in next

=14.71×15=Rs.70.65

It costs 70.65Rs. to buy 4.71m of lace

✔Hence,It is verified:)

Saima wants to put a lace on the edge of a Circular table of Diameter 1.5 m. Find the length of the lace required and also find its cost if one meter of the lace costs ₹ 15. ( Take π = 3.14 )

$\huge{\underline{\mathtt{\red{A} \pink{N} \green{S} \blue{W} \purple{E} \orange{R}}}}$

$\huge\boxed{\blue{Given :}}$

➣ Diameter of the Circular Table Cover = 1.5 m

➣ One meter of the lace costs = ₹ 15

$\huge\boxed{\red{To \: Find :}}$

➣ Length of the lace required

➣ Cost of the lace required

$\huge\boxed{\pink {Solution :}}$

➪ Radius of the Circular Table Cover (r) = $\frac{1.5}{2}$

➦ Circumference of the Circular Table Cover = Length of lace required

➪Circumference of the Circular Table Cover= 2πr

⇒Circumference of the Circular Table Cover = 2 × 3.14 × $\frac{1.5}{2}$

⇒Circumference of the Circular Table Cover = 4.71 m

➦ So, the length of the lace required is 4.71 m.

➪ Cost of 4.71 m lace = Length of the lace required × Cost of lace per meter

⇒Cost of 4.71 m lace = ₹ 4.71 × 15

⇒Cost of 4.71 m lace = ₹ 70.65

➦ So, the length of the lace required is 4.71 m and the cost of 4.71 m lace is ₹ 70.65
