The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2
What is the area of a circle with a diameter of 23cm?
Area = pi*r2r(radius) = diameter/2Radius = 23 cm/2= 11.5 cm-----------------now,Area = pi(11.5 cm)2= 415.5 cm2=========
What is the surface area of a cube that is 2 cm x 2cm x 2 cm?
A cube has 6 faces each face is area 2x2 = 4 square cm surface area = 6 x 4 = 24 sq cm
What is the area of a triangle with base 2cm and 5cm?
Area of a triangle formula: 1/2 x base x height Base = 2 cm Height = 5 cm Area = 1/2 x 2 x 5 = 5 cm^2
What is area of 10cm square?
100 cm(2). (2) means squared
What is the area of a circle with a circumference of 120 cm?
radius = 120/(2*pi) = 19.09859317 cm area = pi*19.098593172 = 1145.91559 or about 1146 square cm
How many diagonals are there in a reactangle?
There are 2
What is the smallest possible perimeter for a shape that has an area of 120 centermetres?
Never heard of centermetres before, and an area cannot be 120 centimetres because that is a measure of distance, not area. Instead, let us start with an area of 120 SQUARE centimetres. For a given area, the shape with the smallest perimeter is a circle. A circle with an area of 120 sq cm would have a radius of 6.18 cm and so a perimeter of 38.83 cm (to 2 dp).
How many 2 cm x 2 cm tiles needed to fill 120 cm x 120 cm space?
3600 of them. Get 4000 to be safe.
What is the perimiter and area of a right triangle with 24cm base and 10cm height?
The area is 0.5*24*10 = 120 square cm. The third side is sqrt(24^2 + 10^2) = 26 cm. So the perimeter is 60 cm.
What is the area of a rectangle whose diagonal is 17 cm with a perimeter of 460 mm explaining work with answer?
The area of rectangle is : 7820.0
Is The area of a rectangle always greater than the perimeter?
To answer this simply try a few out for yourself. In a 2x1 cm rectangle, the area is 2 cm squared and the perimeter is 6 cm In a 12x10 rectangle, the area is 120 cm squared and the perimeter is 44 cm. In some cases, the perimeter is larger and in others it is smaller. To answer your question, no, the perimeter of a rectangle is NOT always greater than its area.
What is the area and its angles of a triangle with sides of 22 cm by 62 cm by 48 cm?
Let its sides be a b c and their opposite angles be A B C and so:- Using the cosine rule angle A = 17.9 degrees Using the cosine rule angle B = 120 degrees Angle C: 180 -17.9 -120 = 42.1 degrees Area: 0.5*48*22*sin(120) = 457 square cm rounded
What is the surface area of a box that is 11cm long and 10cm wide and 12 cm high?
2*(11*10 + 10*12 + 12*11) = 2*(110 + 120 + 132) = 2*362 = 724 sq cm
What is the area of a circle with 120 degrees if the radius is 9 cm?
I assume you want the area of the sector with angle 120o and radius 9 cm: 120o is 120/360 = 1/3 of a full circle. ⇒ area of sector is 1/3 area of full circle ⇒ area_of_sector = 1/3 x π x radius2 = 1/3 x π x (9 cm)2 = 27π cm2 ≈ 84.82 cm2
What is area of a circle with radius of 2 cm?
A circle with a radius of 2 cm has an area of 12.57 square cm.
A tire measures 120 cm around How far does it roll in two revolutions?
The tire moves 2 X 120 = 240 cm.
