Remember the formula of the area of a circle is:
SO given that
V = 226.98
and
Plug in a chug
226.98 = 3.14 *
r = 8.50
Remember that d = 2 * r
d = 2 * 8.5 = 17
Answer:
(x,y) --> (-1, -3)
Step-by-step explanation:
Solve by elimination...
2x - 3y = 7
4x + y = -7 (times 3; so -3y and 3y cancel out)
2x - 3y = 7
12x + 3y = -21
2x = 7
12x = -21
add together...
14x = -14
x = -1
plug x into one of the original equations and solve for y...
-2 - 3y =7
-3y = 9
y = -3
Answer:
m 36.606
Step-by-step explanation:
90*sin24

approximately 37
Answer:
Here, length is 8 in. Width is 4in. and height is (3+3+3)=9 in. Then use the formula.
A= 2wl+2hl+2hw
= 2×4×8 + 2×9×8+2×9×4
=280 inch²
