Answer:
Slope: - 3/4
Step-by-step explanation:
Place your pencil on point y= 4. Go up 3 spaces, then, 4 to the left to the next point.
Slope = - 3/4
( a line going up hill: positive slope. A line going downhill: negative slope)
S2= 864/6
s = = 12 cm
p = 4/3 x 12 = 16 cm
t = 2/4 x 16 = 8 cm
l= 3/4x 16 = 12 cm
lp= 2 (pl+pt+lt)
= 2 (16 x 12 + 16 x 8 + 12 x8)
= 2 (192+128+96) = 832cm²
R= 5
(2-6). -4
—— = ——-
(4-r). (This has to be -1 for the answer to be 4)
4-5=-1
So r=5
Answer:
1256.64
Step-by-step explanation:
To find the area of a circle, the formula is πr2.
R stands for radius, and since the radius of a circle is always half the diameter we can figure this problem out.
If the diameter is 40, the radius is 1/2 of that, so the radius is 20. Now knowing the radius is 20, plug that into our formula and then we'll get the answer.
A = πr2 = π · 20^2 ≈ 1256.63706
≈ 1256.64
