the rectangle shown has a perimeter of 56 cm and the given area. it's length is 8 more than three times it's width. write and so

stiv31 [10]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

Assume width of rectangle be " x ", length = 3×width + 8 = 3x + 8 ~

Now, Perimeter of rectangle is :

$\qquad \sf \dashrightarrow \:2(l + w) = 56$

$\qquad \sf \dashrightarrow \:2(3x + 8 + x) = 56$

$\qquad \sf \dashrightarrow \:2(4x + 8) = 56$

$\qquad \sf \dashrightarrow \:4x + 8 = 56 \div 2$

$\qquad \sf \dashrightarrow \:4x + 8 = 28$

$\qquad \sf \dashrightarrow \:4x = 28 - 8$

$\qquad \sf \dashrightarrow \:x = 20\div 4$

$\qquad \sf \dashrightarrow \:x =5 \: cm$

Hence, width = x = 5 cm

$\qquad \sf \dashrightarrow \:l = 3w + 8$

$\qquad \sf \dashrightarrow \:l = 3(5)+ 8$

$\qquad \sf \dashrightarrow \:l = 15+ 8$

$\qquad \sf \dashrightarrow \:l =23 \:cm$

And, length = 26 cm

Find the height of a cone with volume 4034.66 cm^3 and radius 13 cm.

pav-90 [236]

Volume of cone=4034.66cm^3
Pi×r^2×h/3=4034.66
Pi×13×13×h=4034.66×3
22×13×13×h/7=4034.66×3
h=4034.66×3×7/13×13×22
h=45.57
So h=45.6cm
