I assume you mean the circle's area is 32 square units: area = π x radius2 ⇒ radius = √(area ÷ π) circumference = 2 x π x radius = 2 x π x √(area ÷ π) = 2 x √(area x π) ⇒ circumference =2 x √(32 x π) ~= 20 units.

Total Surface Area of Cylinder = 2 x pi x radius x (radius + height)Surface area of base circle = pi x radius x radiusSurface area of curved part = 2 x pi x radius x heightHence, total surface area = (2 x area of base circle) + (area of curved part)= (2 x pi x radius x radius) + (2 x pi x radius x height)= 2 x pi x radius x (radius + height)

Base Area = pi x radius x radius Curved Surface Area = 2 x pi x radius x height Total Surface Area = 2 x pi x radius x (radius + height)

what is the area of a triangle 2.7 x 5.2 x 6.5

circumference ~= 18.9 ft area = π x radius2 ⇒ radius = √(area/π) circumference = 2 x π x radius ⇒ circumference = 2 x π x √(area/π) ⇒ circumference = √(4 x π x area) ⇒ circumference = √(4 x π x 28.3 ft2) ~= 18.858 ft

The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.

These are some basic formula's;The area of a Triangle:base x height divided by 2.The area of a Square:base x height.The area of a Rectangle:base x height.The area of a Parallelogram:base x height.The area of a Trapezoid:(a + b) divided by 2 x h.The area of a Circle:3.142 x radios.

area = π x radius2 → radius =√(area/π) circumference = 2 x π x radius = 2 x π x √(area/π) = 2 x √(area x π) = 2 x √(121 cm2 x π) = 22 √π cm

You can't tell. The perimeter doesn't tell you the area. There are an infinite number of rectangles that all have the same perimeter but different areas. Here are a few that all have perimeters of 28 cm: 1 x 13 . . . . . Area = 13 2 x 12 . . . . . Area = 24 3 x 11 . . . . . Area = 33 4 x 10 . . . . . Area = 40 5 x 9 . . . . . Area = 45 6 x 8 . . . . .

Base Area = pi x radius x radius Curved Surface Area = 2 x pi x radius x height Total Surface Area = 2 x pi x radius x (radius + height)

area = π x radius2 ⇒ radius = √(area ÷ π) circumference = 2π x radius ⇒ circumference = 2π x √(area ÷ π) ⇒ circumference = √(4π2 x area ÷ π) ⇒ circumference = √(4π x area) So knowing the area, the circumference can be calculated by taking the square root of the area multiplied by 4 times π Example: What is the circumference of a circle with area 78.54cm2 Circumference = √(4π x area) = √(4π x 78.54cm2) ~= 31.42cm
