Answer:
62.8 in2
Step-by-step explanation:
With round pizza we need to
find the area of each pizza in
square inches, then determine
the difference.
The area of a circle is given by:
A = πr2
12 inch diameter, radius = 6
a = π(62) = 36π in2
8 inch diameter, radius = 4
a = π(42) = 16π in2
Difference: 36π - 16π = 20π in2
using 3.14 for pi, the difference is
20(3.14) = 62.8 in2
3x -4 (5 - x) = 7x -20
3x-20+4x=7x-20
7x-20=7x-20
Answer:
225
Step-by-step explanation:
i used a calculater and did 90 divided by .40
The area enclosed is (2x)(600-2x).(2x)(600−2x)=1200x−4x2
In order to maximize we need the derivative to be equal to 0.y′=1200−8x=0
1200=8x
x=150
Therefore the sides for maximum area are 150*300.
<span>The area is: 45000</span>
<span>Simplify the rational expression. State any restrictions on the variable.
A. t + 4; t ≠ 8 B. - t + 4; t ≠ - 8 C. t - 4; t ≠ - 8 D. - t - 4; t ≠ 8
I think it would be C.
