Answer:
160π cm²
Step-by-step explanation:
The area of the shaded region is
area of outer circle - area of inner circle
A = πr₁² - πr₂²
r₁ is the radius of the outer circle = 10 + 3 = 13 cm
r₂ is the radius of the inner circle = 3 cm
A = π × 13² - π × 3²
= π(169 - 9) = 160π cm² ≈ 502.65 cm² ( to 2 dec. places )
I’ll get it correct here :)
He ate 19.95 grams of sugar.

Answer:
1.
Collinear points mean they are on the same line. That leaves us with answer d. F, E, G
2.
In this case, the intersection of the 2 planes is a line. 2 points both planes contain are B and C, so the intersection can be named as answer b: Line BC
3.
2 points define a line, so therefore the answer to the question is answer b. 1
Hoped this helped. If it did, could you please consider giving me a brainliest? :)
Answer:
880 high-quality version
Step-by-step explanation:
I think the below is your full question:
<em>A Web music store offers two versions of a popular song. The size of the standard version is 2.1megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1290 downloads of the song, for a total download size of 4821 MB. How many downloads of the high-quality version were there?</em>
Here is my answer:
Let x is the number of high-quality version
So the number of standard version= 1290 - x
We also know: total download size of 4821 MB. which means:
4.5x + 2.1(1290-x) = 4821
<=> 4.5x+2709-2.1x=4821
<=> 2.4x=2112
<=> x=880
So there were 880 high-quality version
