you multiply 9x9 and you get 81 then you multiply 81x3 = 243
CHEESE!
is it chicken pie?
thats one big pie.
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
Surface area = (2*pi*32) + (pi*6*9)) = 72*pi which is about 226 square cm
18cm 2
You can divide this problem into two steps: 1) Divide the circumference by (2 x pi) to get the radius. 2) Use this radius in the standard formula for the surface area of the sphere.
Area = (pi) x (Radius)2Radius = sqrt(area/pi)Circumference = (2 pi) x (Radius) = (2 pi) x sqrt(area/pi)Circumference = 2 x sqrt(pi x area)

The surface area of a sphere is 4 x pi x r x r so in our case (since we have only half a sphere (hemisphere) the surface ares would be (0.5) x 4 x pi x 9 x 9 =162 x pi square cm. But now you have to add the area of the base because it gets exposed when youcuta sphere (to get the hemisphere) and the area of the base would be pi x r x r = pi x 9 x 9 = 81 x pi square cm. So add the two results to get 243 x pi = 763.4 square cm
Surface area = (2*pi*32) + (pi*6*9)) = 72*pi which is about 226 square cm
7cm x 9cm= 63 sq.cms

18cm 2
The equation for circumference is C = 2*pi*r, where r is the radius of the circle and pi is a constant = 3.14159... Assuming that you mean a 9cm radius, the circumference is therefore: C = 2*pi*r = 2*pi*9cm = 18cm*pi = ~56.549cm
You can divide this problem into two steps: 1) Divide the circumference by (2 x pi) to get the radius. 2) Use this radius in the standard formula for the surface area of the sphere.
It is pi*(92 - 52) = pi*(81 - 25) = pi*56 = 175.93 cm2
Area = (pi) x (Radius)2Radius = sqrt(area/pi)Circumference = (2 pi) x (Radius) = (2 pi) x sqrt(area/pi)Circumference = 2 x sqrt(pi x area)
Area = length x width. In a square these are the same so it is the square of a side, in this case the square of 9...
