Step-by-step explanation:
<u>Formula:</u>

r represents the radius.
The radius is 1/2 of the diameter.
Since 1/2 of 16 is 8, 8 is our radius.
<u>Substitute:</u>

<u>Solve:</u>


The line is leaning to the left, so the slope is negative, eliminate A and D
when x is 3, y is -2, so C is the correct answer
Answer:
V = PI*r^2 h/3
height= 3 * volume / (PI*radius^2)
Answer is B
Step-by-step explanation:
Answer:
£2.80
Step-by-step explanation:
7%= 7/100
(7/100)*40=2.8
Given:
The area model.
The area of the shape is 82 square units.
To find:
The correct equation for the given situation.
Solution:
We know that, area of a rectangle is

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is



Now, the total area is equation to 82 square units.



Since the required equation is
, therefore, the correct option is C.
