What is the formula for finding the area of a semi-circle in terms of pi?
semi means half A semi-circle is half a circle The formula for the area of a circle is A = (Π * r^2) Area of semi circle = (Π * r^2) ÷ 2
How do you calculate area of a bellmouth?
Oh, dude, calculating the area of a bellmouth is like figuring out the size of a weird-shaped pizza slice. You just need to measure the diameter of the bellmouth opening and the height of the curved part, then plug those numbers into the formula for the area of a sector of a circle. It's as easy as eating that pizza... well, maybe not as tasty.
What is formula for area of semi sphere?
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
What is the formula for the area of an ellipse?
The formula for an ellipse is (x/a)2 + (y/b)2 = c2 where a and b are the lengths of the semi-axes and c is a constant.
What is the Formula for the volume of a spherical solid?
A sphere is a revolution of a semi circle about the x axis. The formula for this type of volume is the integral of pi*f2(x)*dx. so if a circle can be described by the formula x2+y2=r2 where r is the radius. so then f(x)=sqrt(r2-x2) so then we square f2(x).... =r2-x2 then we multiply by pi so we have pi*r2 - pi*x2 next we integrate this so have pi*r2x evaluted at r and -r and we also have -(1/3)*pi*x3 evaluted at r and -r once we evalute this we have (4/3)*pi*r3
