Answer:
Radius = 2 cm.
Step by step explanation:
By the Pythagoras theorem the third side of the triangle
= sqrt (6^2 + 8^2)cm = sqrt100 = 10cm.
The formula for the radius of the circle is
r = sqrt [ (s - a)(s-b)(s-c)/ s ] where a,b,c are side lengths and s = the semi perimeter.
Here s = ( 6+8+10) / 2 = 12
So the radius r
= sqrt [ (12-6)(12-8)(12-10)/ 12 ]
= sqrt 4
= 2 (answer).
(1) p x q = 1575
(2) p / q = 9 / 2
divide 1 by 2 to eliminate p:
q^2 = 1575 / (9/2)
q^2 = 350
q = sqrt(350)
Substitue q in either 1 or 2 to find p.
The equation for area is A=l*w
160=10*x (divide out the 10)
x=16
Yes they will. Three bushes will need 12ft. and the longer side is 16ft.
Answer:
(x+2)^2 + (y+10)^2 = 100
Step-by-step explanation:
y = 6x + 2
Z(-2,0)
x = -2
y = 6 x (-2) + 2
y = -12 + 2
y = -10
M(-2, -10)
r = 0 - (-10) = 10
(x + 2)^2 + (y + 10)^2 = 100
