Find the area of the shaded region 40 degrees and raduis 9 cm in a circle use pi 3.14?
Sure thing, darling! To find the area of the shaded region in a circle with a central angle of 40 degrees and a radius of 9 cm, you first calculate the area of the entire circle using the formula A = πr^2. Then, you find the fraction of the circle that the shaded region represents, which is 40/360. Multiply this fraction by the total area of the circle to get the area of the shaded region. Easy peasy lemon squeezy!
How many square feet are in a 40 foot diameter circle?
Oh, dude, you're hitting me with some math here! So, the area of a circle is π times the radius squared. If the diameter is 40 feet, the radius is 20 feet. Plug that into the formula, and you get an area of 400π square feet. But who's really counting, right?
What is the surface area of a cone with a slant height of 40 and a radius of 20?
A slant height of 20 and base circle radius (r) of 20 gives slant length (s) = 28.284 equation for cone surface area : (pi * r * s) + (pi * r2) = 1777.136 + 1256.637 = 3033.773 units2
