Question

A round table cover has six equal designs as shown
in Fig. 12.14. If the radius of the cover is 28 cm, find
the cost of making the designs at the rate of
0.35 per cm². (Use V3 = 1.7)​

Answer 1

Answer:

answer is 33

l hope its help uh

Answer 2

Answer:

Step-by-step explanation:

area of segment=$r^{2}$($\frac{∅}{360}$π-sin$\frac{∅}{2}$cos$\frac{∅}{2}$)

there are 6 designs so ∅=$\frac{360}{6}$=60

area of 6 designs are 6*28*28($\frac{60}{360}$$\frac{22}{7}$-sin30cos30)

=6*28*28($\frac{1}{6}$$\frac{22}{7}$-$\frac{1}{2}$$\frac{[tex]\sqrt{3}$}{2}[/tex])

=$\frac{28*23}{5}$

cost =area*.35

$\frac{28*23}{5}$*0.35

=$176.68
