The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
56.549 cm
It is 28.3 cm, approx.
Doubling the radius doubles the circumference.
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
The surface area is 226.2cm2
Length = 9cm and total surface area is 486cm2
56.549 cm
The formula for the surface area is 2lw + 2hl +2hw. So, 2(9*12)+2(9*12) +2(9*9)=?
The circumference of a circle that is 9 cm wide is: 28.274 cm
56.549 cm
It is 28.3 cm, approx.
Doubling the radius doubles the circumference.
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
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
Circumference of the circle: 2*pi*9 = 18*pi cm
