Question

Shalini has to cut out circles of diameter 1¼cm from an aluminium strip of dimensions 8¾cm by 1¼ How many full circles can Shalini cut? Also calculate the wastage of aluminium strip.​

Answer 1

Answer:

7 number of circles

wastage = 2.347 cm^2

Step-by-step explanation:

okay, so given diameter of the circle as 1 1/4 and one dimension of the aluminium strip same as 1 1/4. So you just have to divide the 8 3/4 over 1 1/4 which gives you 7.

wastage would be the total area of the aluminium strip minus the area of the total Circles. That is, 10.9375 - 8.59029

= 2.347 cm^2
