when radius = 4 cm
area = 3.14*4*4=50.24 cm2
A square with an area of 16 square centimeters has side lengths of 4 centimeters, as the area is calculated by squaring the length of one side (4 cm × 4 cm = 16 cm²). This shape's area is indeed not 12 square centimeters. Additionally, other shapes such as a rectangle with dimensions of 4 cm by 4 cm also meet this criterion, as long as their area equals 16 cm² and not 12 cm².
4 cm is equal to 40 mm. To convert centimeters to millimeters, you multiply by 10 since 1 cm is equal to 10 mm.
The surface area of a cube is given by 6 times the side length squared, which equals 6 x (4 cm)^2 = 96 cm^2. The volume of a cube is the side length cubed, which is 4 cm x 4 cm x 4 cm = 64 cm^3. Therefore, the surface area to volume ratio is 96 cm^2 / 64 cm^3 = 1.5 cm^-1.
The surface of a sphere is: A=4? r2 From this, the surface are changes as the square of the radius. It does not change linearly.
That is a good approximation. The actual answer is 3.937 inches. One centimeter is equal to .3937007878 inches, usually rounded to .394. To convert centimeters into inches, multiple the centimeters by .393700787.
4 cm radius = Area of 50.26548 sq. cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square cm
Area circle = π × radius² Area smaller circle = π × (4 cm)² = 16π cm² Area larger circle = π × (10cm)² = 100π cm² → probability inside smaller circle = area_smaller_circle/area_larger_circle = 16π cm²/100π cm² = 16/100 = (4×4)/(4×25) = 4/25.
Area = pi*radius-squared. Therefore, area = pi*4*4 sq cm = 50.27 sq cm.
The area of a circle = pi x radius squared where pi = 3.1416 therefore area = 3.1416 x 4 x 4 = 50.26 square cm
Area = pi*42 = 50.26548246 or about 50 square cm
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
This indicates a radius of 4 cm, in which case the area of the circle is: 50.27 square cm
The area is about: 50.27 square centimeters.
