A circle with radius of 4 cm sits inside a circle with radius of 11 cm.
2 answers:
The area of the shaded region = 330 sq cm
Step-by-step explanation:
Given,
The radius of small circle (r) = 4 cm
The radius of large circle (R) = 11 cm
To find the shaded region
Formula
The area of circle of radius r = π sq cm
So, The radius of the small circle = π× sq cm = 16π sq cm
The radius of the large circle = π× sq cm = 121π sq cm
Hence the area of the shaded region = 121π-16π sq cm
= 105π sq cm
= 105 × sq cm = 330 sq cm

Round answer to the hundredth:
So, a line parallel to <span>y - 5x = 10, will have the same slope as that equation, so what is that slope anyway? let's solve for "y".

<span>
alrite, so the slope is 5 then, well, then the parallel line will have the same slope.
so, we're really looking for the equation of a line whose slope is 5 and runs through 3,10.
