225 cm squared
Area = pi*7.52 = 176.715 square cm rounded to 3 dp
15*15 = 225 square centimetres.
The area of a square is given as the square of a side. So simply take the square root of the area for a side.
1 side of square = 2cm area of square = side x side so, area= 2x2 = 4 cm^2
Well, darling, to find the area of a triangle with those side lengths, you can use Heron's formula. So, plug in those side lengths (a=8, b=11, c=15) into the formula, calculate the semi-perimeter, and then solve for the area. Voilà, you've got yourself the triangle's area.
15cm
A square with a side length of 15 cm has an area of 225 square cm
The area of square is : 225.0
Each side is the square root of 225 equals 15cm and its perimeter is 4*15 = 60cm
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.
The surface area of a 15cm plate can be calculated using the formula for the surface area of a circle, which is A r2. Since the plate is circular, the radius (r) would be half of the diameter, which is 15cm. Therefore, the surface area would be A (7.5)2 176.71 square centimeters.
sqrt(15) = 3.873 cm (approx)
Area = pi*7.52 = 176.715 square cm rounded to 3 dp
Area = 0.5*3.4*15 = 25.5 square cm
Area = 1/2*14*15 = 105 square cm
Area = (pi) (radius)2 = 225 pi = 706.858 square centimeters (rounded)
Area of the triangle = 0.5*base*height = 0.5*10*15 = 75 square cm Area of the rectangle = base*height = 10*15 = 150 square cm
