Question

serena has a trampoline whose area is 250 4.34 square cm what is the radius of the trampoline​

Answer 1

Answer:

The radius of trampoline is 28.21cm

Step-by-step explanation:

Let, radius of trampoline is r cm

Here, the area of trampoline is 2504.34 CM. square

ATQ,

$area \: of \: trampoline = pi r^{2}$

$2504.34 = \: \:\pi \: r ^{2}$

or

$r ^{2} = 2504.34 \times 7 \22$

$r ^{2} = 796.835$

or,

$r = \sqrt{796.835}$

$r = 28.21 cm$

so, radius of trampoline is 28.21 cm
