I'm wondering what the original, or book, question actually asks, but in this case, a it is a circle larger in radius, diameter and circumference by the ratio 4:3; and in area by the ratio 16:9.
what does 16 by14 mm look like
The circumference of a circle that is 16 mm in diameter is 50.27 mm
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
Well, darling, a 2 mm circle looks like a tiny dot, barely visible to the naked eye. It's smaller than a grain of sand, so good luck trying to spot it without a magnifying glass. Hope that clears things up for you, sugar.
If the circle's circumference is 58 mm then its diameter is 58/pi which is about 18.462 mm
A 10 mm diameter object would appear as a circle with a width of 10 millimeters when viewed directly from above. To put it into perspective, a common comparison is that a standard pencil's diameter is around 7-8 mm. So, a 10 mm diameter object would be slightly larger than a pencil's width.
what does 16 by14 mm look like
A 4 mm circle would have a diameter of 4 millimeters, meaning the distance across the circle passing through its center would be 4 mm. This circle would be relatively small, about the size of a standard pencil eraser. In terms of area, the circle would cover approximately 12.57 square millimeters.
Oh, dude, you're hitting me with some math here. So, the circumference of a circle is calculated by multiplying the diameter by pi (π). Since the diameter of a circle is twice the radius, and you've given me the radius (40 mm), I can tell you that the circumference of a 40 mm circle would be approximately 251.2 mm. It's like math, but with a side of sarcasm.
The circumference of a circle with a diameter of 110 mm is 345.58 mm
The circumference of a circle that is 16 mm in diameter is 50.27 mm
The diameter of a circle that has a circumference of 113 mm is about 35.97 mm
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
Oh, dude, you just gotta divide the diameter by 2 to get the radius, which is 120 mm. Then you square that bad boy to get 14,400 mm². So, like, the area of the circle is 14,400 mm². Easy peasy, lemon squeezy.
Well, darling, a 2 mm circle looks like a tiny dot, barely visible to the naked eye. It's smaller than a grain of sand, so good luck trying to spot it without a magnifying glass. Hope that clears things up for you, sugar.
A circle with a radius of 50 mm has an area of 7853.98 square mm
A circle with a radius of 6 mm has a circumference of 37.7 mm
