Ah, what a lovely question! To find the circumference of a cylinder, you'll want to use the formula 2πr, where r is the radius of the cylinder. Since the diameter is 16 inches, the radius would be half of that, which is 8 inches. So, the circumference would be 2 x π x 8, which is approximately 50.24 inches. Keep painting with those happy little numbers!

What is the radius of a 15cm circle?
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
A circle has a circumference of 94.2 centimeters Its diameter is 15 centimeters which expression can you use to find the approximate value for pi?
You've stated an impossible question. If a circle has a circumference of 94.2 cm, it has a diameter of 30 cm. If it has a diameter of 15cm, it has a circumference of 47.1 cm.circumference = 2 * pi * radius = pi * diameterIf you had stated the question correctly (changed circumference to 47.1 cm OR changed diameter to 30 cm OR changed "diameter" to "radius"), then the answer would be:pi = circumference / diameter = (e.g.) 94.2 cm / 30 cm
What is the area of a triangle with a base of 10cm and a height of 15cm?
To find the area of a triangle, you use the formula: Area = 1/2 * base * height. Plugging in the values, we get Area = 1/2 * 10cm * 15cm = 75 square cm. Therefore, the area of the triangle with a base of 10cm and a height of 15cm is 75 square cm.
