3. 283.53
4.254.47
5. 63.62
6. 380.13
Step-by-step explanation:
do πr²
r = radius
if you have a diameter like question 4 divide by 2 and you get radius
Answer:
Givens:
Using this information we could recur to SAS postulate to demonstrate the congruence of this pair of triangles. We already have one side and one angle congruent, we just need to demonstrate that 
, that will prove the complete congruence.
So, based on the given coordinates, we're able to calculate the length of each side and find if they are the same. We use this formula:
Therefore, , because they have the same length.
Now, based on these congruences:
We demonstrate by the Side-Angle-Side (SAS) postulate that ΔABC ≅ ΔDEF.
Answer:
The next in the first pattern is 15.
The next in the second pattern would be 3.
The next in the third pattern would be 32.
Step-by-step explanation:
In the first pattern, you can notice that the terms keep going up by 3. As a result, the next one is 3 higher (12 + 3 = 15)
In the second pattern, the next number is always half of the number before it. (6 * 1/2 = 3)
The last pattern shows each number being 10 less than the one before it. (42 - 10 = 32)
There are several ways to answer this question and I will use this approach. Since Johnny reads at a ratio of 7:3 it can be stated that for every 10 pages in a book containing 500 pages Johnny will read 7 of those pages. There are 50 groups of 10 in a 500-page book (50 x 10). Take the ration 7:3 times 50 and use the distributive property: 7:3(50) = (7 x 50):(3 x 50) = 350:150. Based on this Johnny has read 350 pages and has 150 pages remaining.
