Answer:

C-42

B-156

A-66

Step-by-step explanation:

Now I'm not a 100% sure on this but I'm pretty confident.

The easiest on to find was C because on the opposite side was 24 so the side we are working with must equal 24. In order to find the answer I did 24 + 18 and got 42. That means C = 42.

The next one I found was B. A straight line is 180 degrees so I subtracted 24 from 180 and got 156.

Finally I found A. This was considerably the quickest on to find for me because of all the other measurements I found and the 90 degrees beside the A. I subtracted 90 from the already found 156. I got 156 because if you take out the 90 degree line it would be a mirror image of B. Once I subtracted 90 from 156 I got 66 as my answer.

The area of the curved surface of a cylinder is 6160cm. The height of the cylinder is 10cm. What is the radius of the cylinder i

valina [46]

Answer:

r = 98 cm

Step-by-step explanation:

Formula for curved surface area = $2\pi rh$

where r = radius & h = height

Let the radius be 'r'.

According to the question ,

$6160 = 2 \times \pi \times r \times 10$

$= > 20\pi r = 6160$

$= > r = \frac{6160}{20\pi} = \frac{6160 \times 7}{20 \times 22} = 98cm$

Find the prime factorization of 108

Nimfa-mama [501]

Answer:

2^2 * 3^3

Step-by-step explanation:

When breaking of 108 into factors, you first get 9 and 12. Then, the 9 gets split into a 3 and a 3. Meanwhile the 12 is split into a 3 and a 4. Finally the 4 is split into a 2 and a 2. So you end up with 2*2*3*3*3, which is the same as 2^2 * 3^3
