Answer:
477.28cu m
Step-by-step explanation: R (8) x3.14 (pi) is 25.12, 25.12x19=477.28
Answer:
-1 is the only answer that is greater than -5
Answer:
the x distance is 9 - -4 = 9+4 = 13
7/10 of that is 91/10 = 9.1
-4 + 9.1 = 5.1
the y-distance is 6 - -5 = 6+5 = 11
7/10 of that is 77/10 = 7.7
-5 + 7.7 = 2.7
so ( 5.1, 2.7) is hte point that is 7/10 of the distance. Please label this point M.
the distance of AB is sqrt( 11^2 + 13^2) = sqrt(121+169) = sqrt(290) , or approximately 17.0294
the distance from A to M is sqrt( 9.1^2 + 7.7^2) , or approximately 11.92
the quotient of these distances is 0.7 approximately
Step-by-step explanation:
Find the coordinates of the point seven tenths of the way from A to B.
the coordinates of b is (-4,-5)
the coordinates of a is (9,6)
Answer:
The correct answers are a, c and d
Step-by-step explanation:
The formula for the volume of a sphere is the following:

Plug in V=5000π and solve for the radius.

Divide both sides by


Multiply both sides by 3/4 (to eliminate the 4/3 on the right side)
Also, flip the equation so we have the unknown variable on the left side (math etiquette).

Take the cube root of both sides

Now, calculate the surface area since now we know the radius.
The formula for the surface area is the following:

Plug in r=15.5

The second choice is your answer.
