Circumference of the smaller circle, using
, is approximately equal to 18.85 (I used the high floating point precision approximation of pi my calculator has in memory, then rounded to 2 decimal points.)
Using the formula
, which in English says "the smaller circle's circumference is equal to 20% of the larger circle's", we can substitute the known value S:
and solve for L:
.
So the larger circle has a circumference approximately equal to 92.5 units.
Answer:
vertex (-4,-1)
2nd point ( 0,31)
Step-by-step explanation:
f(x) = 2x^2 + 16x + 31
First find the vertex
The x coordinate of the vertex is -b/2a where ax^2 +bx +c
-16/ 2(2) = -16/4 = -4
Substitute into the function
f(-4) = 2 ( -4)^2 +16(-4) +31
= 2 *16-64 + 31
= 31 -64 +31
= -1
The vertex is at ( -4,-1)
Another point can be x=0
f(0) = 0+16(0)+31
= 31
( 0,31)
The answer is 43.95 in ≈ 44 in
Step 1. Sum up their wingspans which will reflect the perimeter of the tree they wrap.
Step 2. From the calculated perimeter in step 1, find the diameter.
Step 1.
Perimeter of the tree is the sum of their wingspans:
P = 5'6'' + <span>6'
5'6'' = 5 * 12 in + 6 in = 66 in
6' = 6 * 12 in = 72 in
P = 66 in + 72 in = 138 in
Step 2.
Perimeter of a circle with radius r is:
P = 2 r </span>π
Since diameter is twice of radius (d = 2r), then
P = d * π
P = 138 in
π = 3.14
138 in = d * 3.14
d = 138 in / 3.14
d = 43.95 in ≈ 44 in

I have made it in a pic look at this
Answer:
c+y peaches
Step-by-step explanation:
since the questions does not mention any peaches that are left over even after Andrew took the y peaches, the c amount and y amount are all that were on the plate.
