Work out the area of a semi circle with a radius of 3cm give your answer in terms of pi

Ivenika [448]

<h3>The area of semicircle is $4.5 \pi\ cm^2$ </h3>

Solution:

Given that,

We have to find the area of a semi circle with a radius of 3 cm

The area of semicircle is given as:

$Area\ of\ semicircle = \frac{ \pi r^2}{2}$

Where, r is the radius

From given,

r = 3 cm

Substituting the values we get,

$Area\ of\ semicircle = \frac{ \pi \times 3^2}{2}\\\\Area\ of\ semicircle = \frac{ \pi \times 9}{2}\\\\Area\ of\ semicircle = 4.5 \pi$

Thus the area of semicircle is $4.5 \pi\ cm^2$

Identify this conic section.

BaLLatris [955]

Solve for x or y or 1
solving for y
divide both sides by x
y=25/x
not a line because x has t ohave exponent of 1, this one is y=25x^-1

ok, solve for something else
solve for 1
xy/25=1
this doesn't fit into the standard forms of any of the conic sections
if we were to subsitute points we would see it is a hyperbola that is diagonal with the x and y axises as assemtots

it is a hyperbola
