The surface area of a whole sphere, of radius r, is 4*pi*r2.The area of the curved surface of a hemisphere is, therefore, 2*pi*r2.The area of the flat surface is that of a circle of radius r, that is = pi*r2.So the total surface area of a hemisphere is 2*pi*r2 + pi*r2 = 3*pi*r2.
To find the diameter of a circle you multiply the radius by 2 or d=r2
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
It is pi*r2*h where r is the radius of the tank and h is the height of the liquid.
pi(r2)of inner minus pi(r2) of outer. multiply height= volume or you could drop it in a beaker and see how much water was displaced
1/2*pi*r2
Area = pi*[R2 - r2] where R is the outer radius and r the inner radius.
Ï€*r2, where r is the radius of the circle.
multiply r2+7r+10/3 by 3r-30/r2-5r-50 weegy
The surface area of a whole sphere, of radius r, is 4*pi*r2.The area of the curved surface of a hemisphere is, therefore, 2*pi*r2.The area of the flat surface is that of a circle of radius r, that is = pi*r2.So the total surface area of a hemisphere is 2*pi*r2 + pi*r2 = 3*pi*r2.
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
To find the diameter of a circle you multiply the radius by 2 or d=r2
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
Because the perimeter (circumference) is 2*pi*r is proportional to r. The area a = pi * r2 is proportional to r2
It is pi*r2*h where r is the radius of the tank and h is the height of the liquid.
