Answer:
C. 7790.83 cm^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
We know the radius is 12.3
Using 3.14 for pi (This will give us an approximation, not an exact value)
V = 4/3(3.14) (12.3)^3
=7790.82984 cm^3
Answer:
Answer for 4th question
b = 7
Answer for 5th question
area= 99sq.in
Step-by-step explanation:
4. area of parallelogram= base × height
28= b × 4
b= 28/4
b = 7
5. area of parallelogram= base × height
area= 9 × 11
area= 9 sq.in
Answer:
<u>18 kilometers</u>
Step-by-step explanation:
if you know the perimeter, then all you have to do is add up what you have, 10+7=17 and then subtract it giving you the bits that you dont know, so 35-17=18 kilometers.
Answer:
72 sheets
Step-by-step explanation:
We can use the proportion: <em></em>.
Cross-multiplication shows us that <em>5x = 360</em>.
This means that x = 72 sheets.
(There are simpler methods, but this is the most easily explainable)
Hello!
Explanation: <u><em>This question is super easy for me. First you had to do add 1 from both sides. It gave us -1-4s+1=8+1, then simplify, and it gave us -4s=9. You can also divide by -4 from both sides. It gave us -4s/-4=9/-4, and simplify. And the answer it gave us is s=-9/4 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie </em></u>
