Answer:
138.16 in²
Step-by-step explanation:
The surface area SA of the cone is the sum of the base area B and the lateral area LA. The lateral area is half the product of the circumference and the slant height. The radius is half the diameter, so is 4 inches.
SA = B + LA
= πr² + (1/2)(2πrh) . . . . where h is the slant height
= (πr)(r +h)
Filling in the numbers, you have ...
SA = (3.14)(4 in)(4 in + 7 in) = 3.14×(44 in²) = 138.16 in²
The rate of change of the area of the triangle when t=1 is also equal to 3.
<h3>Rate of change</h3>
Given the function of height of a triangle expressed as:
The rate of change is expressed as
The rate of change of the area of the triangle when t=1 is also equal to 3.

The expression which can be used to solve this problem is 5.50h + 1.5h.
Since the given data is 44.5 hour week, all we need to do is substitute the given data to the expression. Since it takes 56 hours a week for a complete office/working hour without overtime, Joel's 44.5 hour week means he did not have overtime hours. Therefore the solution is,
5.50(44.5) = 244.75 Dollars.
Answer:
Option C - 2(-5)+2(3) ; -4
Step-by-step explanation:
Distributive property means breaking up the factors and multiplying them separately
So here we have 2(-5+3) = 2(-5)+2(3) = (-10)+(6) = (-4)
So (-4) is the value.
Hope this helps you.
Answer:
13
Step-by-step explanation:
In inches, the height of the ceiling is ...
(15 ft)(12 in/ft) = 180 in
The number of times 13.25 inches will fit in this space is ...
(180 in)/(13.25 in) ≈ 13.6
Betty can fit 13 whole boxes in the space.
