To find the curved surface area of a cone multiply the base radius of the cone by pi.
Then multiply your answer by the length of the side of the cone.
So 5 x pi x 8.2 = 128.81 (2 decimal places)
The surface area of the bottom of the cone is given by pi x radius2.
pi x 52 = 78.54 (2 decimal places)
So the total surface area = 128.81 + 78.54 = 207.35 cm2 (2 decimal places)
2 feet and 8 inches
Assuming you meant area of 40 cm2, the rectangle would need to be 40 cm x 1 cm
An isosceles triangle can be considered as being two right angled triangles joined together and if we divide the base by 2 this gives us two adjacent sides of 18cm. By rearranging Pythagoras' Theorem we can calculate that the opposite side or perpendicular height of the triangle is 80cm: Pythagoras' Theorem: 822-182 = 6400. The square root 6400 is 80. Tangent = opposite/adjacent 77.31961651o = 80/18 Alternatively the Cosine ratio can be used: Cosine = adjacent/hypotenuse 77.31961651o = 18/82 Or even the Sine ratio: Sine = opposite/hypotenuse 77.31951616o = 80/82 Therefore the isosceles triangle has two equal base angles of 77.32 degrees correct to two decimal places.
82cm in m is 0.82 m.

82cm = 32.2835 inches.
The height of koalas from the northern parts of Australia ranges between 74cm for males and 72cm for females. Koalas in the southern states are larger, and can grow to 82cm for males and 73cm for females.
(820mm)/(10mm/cm)=82cm
82 cm = 820 mm
82 cm / 2.54 = 32.28in
The paper size is equivalent to A1 paper, which measures 594mm x 841mm.
82 cm is less than 1 m82 cm < 1 m
