The rule of surface area for the cone is
Pi r^2+2pi L
This means
pi*7^2+ 7*pi*9=352 feet^2
Answer:
52/48 , or 1.083333333333333 hours.
Step-by-step explanation:
Both the functions have the same slope which is 2.
Answer:
Step-by-step explanation:
AR = QR = RS = (1/2) QS = 3
So ....by the Pythagorean Theorem, AS = AQ =
√ [3^2 + 3^2] = √[9 + 9 ] = √18
And the area of the two semi-circles= the area of a circle with a radius of AS/2 =
pi [AS/2]^2 =
pi [√18/2]^2 = 18pi/4 = (9/2)pi units^2
And the area of the rest of the figure is just that of a rhombus =
The product of the diagonals / 2 =
AB*QS/2 = 9 * 6 / 2 = 27 units^2
So....the total area =
[(9/2) pi + 27] units^2 = about = 41.1 units^2 [rounded]
All the linear functions in form y = mx + b where m ≠ 0 has the inverse in form
y = x/m - b/m.
Answer: The inverse of f exist.
