If you need to know area of a circle then it is: pi*4^2 = 16*pi square cm or about 50 square cm
You need 8 cm to measure 8 cm.
To find the diameter of a circle with an 8cm circumference, you can use the formula C = πd, where C is the circumference and d is the diameter. Plugging in the given circumference of 8cm, you get 8 = πd. To solve for d, divide both sides by π, giving you d = 8/π. Therefore, the diameter of a circle with an 8cm circumference is approximately 2.55cm.
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
We know that area of square. = 64 c m 2. Hence area of square.
Multiply the diameter by the value of Pi - and you'll have your answer !
It should be 8 cm.
radius=4cm diameter=8cm *radius is half the diameter
Circumference of a circle = 3.14 x d 3.14 x 8 = 25.12 Therefore the circumference of a circle with the diameter of 8cm is 25.12cm.
The volume of a sphere with a diameter of 8cm is about 268cm3
32 cm² = 8cm²/2
It has a circumference of 50.3cm
C = ~25.133 cm
