Answer:
Step-by-step explanation:
Circle = pi*r^2
Diameter = 80, so radius = 40
Circle = pi*40^2 = pi*1600 is approximately 5026.55 yards
Answer:
probably it
Step-by-step explanation:
First, get the area of the rectangle then subtract the triangle, the result will be the shaded area:
area rec = 18 * 11
area rec = 198 cm²
small side of tri = 11 - 5
small side of tri = 6 cm
area tri = (height * width) / 2
area tri = (6 * 18) / 2
area tri = 108 / 2
area tri = 54 cm²
area shaded = 198 - 54
area shaded = 144 cm²
Answer:

This is the concept of algebra, the revenue of the smart phone sells is given by:
revenue=cost+profit
cost of producing an phone is:
C(x)=2x+35
Profit is given by the function:
P(x)=-x^2+120x-435
Thus the revenue will be:
R(x)=-x^2+120x-435+2x+35
R(x)=-x^2+122x-400
The answer is A
