Answer:
(a)f(4) square cm.
(b)f(10.91)-f(10.9) Square centimeter.
Step-by-step explanation:
f(r)=the area of a circle (in square cm) that has a radius of r cm.
(a)Area (in square cm) of a circle whose radius is 4 cm.
Since r=4cm
Area of the circle = f(4) square cm.
(b) When the radius of the increases from 10.9 to 10.91 cm.
- Area of the circle with a radius of 10.91 = f(10.91) square cm.
- Area of the circle with a radius of 10.9 = f(10.9) square cm.
Change in the Area = f(10.91)-f(10.9) Square centimeter.
Answer:
<em>14</em>
Step-by-step explanation:
<em>The answer is 14 because it shows one on 2 and 3 on 4. You add 4 + 4 + 4 which equals 12 then you add 12 + 4 which equals 14. Therefore, the answer will be 14.</em>
Answer:
VX = 4n +7
explanation:
the equation is VX = n + 7 + 3n, all you need to do is add the n variables and get VX = 4n + 7.
The question is set up oddly, but if they mean that one of the interior angles of a triangle measures 52degrees, what is the measure of its exterior angle, the you’d do the following: 180 (since they would form a linear pair) - 52 = 128 degrees.
