Well, honey, if the diameter of a circle is 7 mm, then the radius is half of that, which is 3.5 mm. The formula for the area of a circle is πr^2, so plug in 3.5 for the radius and you get an area of approximately 38.48 square millimeters. So there you have it, darling!
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.
Diameter = 2 x radius = 18 mm .
It is: 1060/2 = 530 mm
2 * pi * 17
The formula, when the radius is known, is: A = PI(r)2 A circle with a radius of 450 mm has an area of 636,172.51 square mm.
The formula to calculate the area of a circle is A = πr^2, where r is the radius. Since the diameter is given, we can find the radius by dividing the diameter by 2. So, the radius would be 13.2 mm / 2 = 6.6 mm. Plugging in this value, the area of the circle is approximately 136.62 square millimeters.
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
13 mm. The radius of a circle is 1/2 of the diameter.
Well, honey, if the diameter of a circle is 7 mm, then the radius is half of that, which is 3.5 mm. The formula for the area of a circle is πr^2, so plug in 3.5 for the radius and you get an area of approximately 38.48 square millimeters. So there you have it, darling!
Well, darling, the area of a circle is calculated using the formula A = πr², where r is the radius. So, if the radius is 42 mm, plug that bad boy in and you'll get an area of approximately 5,539.82 square millimeters. Just remember, math doesn't care about your feelings, it's all about those numbers.
Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
The radius of a circle is half of its diameter. Therefore, if the diameter is 50 mm, the radius would be 50 mm ÷ 2 = 25 mm.
radius = square root of (75/pi) = 4.886025119 diameter = 2*radius = 9.772050238 or 10 mm to the nearest integer
To calculate the area of a screw with a diameter of 50 mm, we can use the formula for the area of a circle: ( A = \pi r^2 ), where ( r ) is the radius. The radius is half of the diameter, so ( r = 25 ) mm. Plugging this into the formula gives ( A \approx \pi \times (25)^2 \approx 1963.5 ) square mm. Thus, the area of the screw's cross-section is approximately 1963.5 mm².
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.
