Find the diameter of a circle that has an area of 254.34mm2

Mathematics
1 answer:
zvonat [6]3 years ago
5 0
To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient

\frac{254.34}{3.1415} =  80.95
\sqrt{80.95} = 8.99
That is the radius now just times that by 2 so 2 x 8.99 = 17.98

Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18

A triangle has sides with lengths of 3 feet, 6 feet, and 8 feet is it a right triangle?
Zielflug [23.3K]

Answer:

Solution,\\Longest~side(h) = 8ft.\\Perpendicular(p) = 3ft.\\Base(b) = 6ft.\\Now, \\h^2 = (8)^2 = 64sq.ft.\\p^2+b^2 = 3^2+6^2 = 9+36 = 45sq.ft.\\Since, h^2\neq p^2+b^2, ~the~triangle~is~not~a~right~triangle.
