What percent of a circle is 1/4 + 1/2 ?

zlopas [31]

Presuming the circle is the whole, 1/4 + 1/2 is 3/4, or 0.75, so it is 75% of the circle.

Write the equation of the circle with center (2, -3) and a radius of 4.

harkovskaia [24]

C(h,k) radius(r)
C(2,-3) r=4

(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16

therefore, the answer is D

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

zvonat [6]

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
