A ≈ 28.27cm2
A cylinder with a height of 7cm and a diameter of 6cm has a surface area of 188.5cm2
The exact area = pi*32 or 9*pi square cm
113.1 cm3
radius=1/2 diameter so R=3cm
A ≈ 28.27cm2
The area is 28.274 cm2
The circumference of a circle with a diameter of 6cm is about 18.85cm
A cylinder with a height of 7cm and a diameter of 6cm has a surface area of 188.5cm2
A sphere with a diameter of 6cm has a volume of 113.1 cm3
The exact area = pi*32 or 9*pi square cm
Area of a circle = (pi) R2 = (pi) x (1/2 of the diameter)2 = 9 pi = 28.27 cm2 (rounded)
12 cm.
113.1 cm3
12 cm
The diameter of circle A is 12cm so its radius must be 6cm.
radius=1/2 diameter so R=3cm
