The curved surface area is 89.76527 units2 and the total surface area is 134.6479 units2
is the formula for volume of a sphere.Now just plug in 3 for r. You should get 36pi
you need to work backward for find the radius from the volume then work forward and find the surface area. The volume is 36 Pi cm3 The formula for the volume inside of a sphere is 4/3 Pi x radius3 so 36xPi=4/3 Pi x radius3 So 108/4=the radius3 so 27 is the radius cubed hence 3 is the radius. This tells us the surface area is 4xPix32 =36Pi cm squared. So in the surface area is also 36 but the units are square cm.
Formula: 4πr2 Surface Area = 113.09734 units2
A=pi*radius^2 so 12/2=6 ==> radius so 36pi square feet is the area
area = πr2 ⇒ r = √(area/π) ⇒ r = √(36π/π) = √36 = 6 circumference = 2πr = 2 x π x 6 = 12π
is the formula for volume of a sphere.Now just plug in 3 for r. You should get 36pi
Surface area = 4*pi*32 = 36pi square cm
It is: 6 cm because pi*62 = 36pi square cm
Vol=pi*r2*h =pi*6squared*8 =36pi*8 =288pi
As a cell becomes larger, its volume increases faster than its surface area. This results in a decrease in the surface area to volume ratio. A high surface area to volume ratio is important for efficient exchange of nutrients and waste with the cell's environment.
