Answer: it is -97
Step-by-step explanation:
because you break it down
-1-81-16+1 ( and the -- turns into a + )
( get rid of the + )
Step-by-step explanation:
A. 18√2
= 25.4558441227
B. 18/√3
= 6√3
= 10.39230485
C. 18√2 /√3
= 6√6
= 14.69693846
D. 18 · √3 / √2
= 9√6
= 22.04540769
First you plug in the variables:
(-3)(2)+(6)(-3)(4)
Multiply:
-6+(-18)(4)
-6+-72
Add and your answer comes out to be:
-78
Answer:
2,144.7
Step-by-step explanation:
The formula for the volume of a sphere is V=4pi r^3/3. Lets apply this formula for your sphere. The radius is 8, so lets plug in 8 in our formula. 4pi 8^3/3. Now, lets solve. 4 times pi. What is pi? We usually think of pi as 3.14. 4x3.14 is 12.56. Now, lets do 8^3/3. 8 times 3 is 512, and divided by 3 is 170.67. Alright, now we have 12.56 times 170.67. That is 2144.7 rounded to the nearest tenth.
