The volume of a sphere is 2145 cubic centimeters. What is the approximate diameter of this sphere?
eimsori [14]

Answer:

d = 2(40.11 cm) = 80.22 cm

Step-by-step explanation:

The formula for volume of a sphere is V = (4/3)πr³

and here V = (4/3)πr³ = 2145 cm³

Let's simplify this equation by multiplying both sides by (3/4); this will cause (4/3) to disappear:

(3/4)(4/3)πr³ = (3/4)2145 cm³, or

                 r³ = 1608.75 cm³

Taking the cube root of both sides, we get:

                  r = 40.11 cm

Remembering that diameter = 2 times radius, we calculate the diameter:

                  d = 2(40.11 cm) = 80.22 cm

The roof rafter of a house has been raised to a height of 13 yards at the ridge. Half of the length of the run measures 9 yards.
dimulka [17.4K]

Answer:

15.81 = ?

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

9^2 + 13^2 = ?^2

81 +169 = ?^2

250 = ?^2

Taking the square root of each side

sqrt(250) =?

15.8113883= ?

To the nearest 100th

15.81 = ?

lions [1.4K]
12y - 7x = 5......(1 , ?)....when x = 1....so we sub 1 in for x
12y - 7(1) = 5
12y - 7 = 5
12y = 5 + 7
12y = 12
y = 12/12
y = 1........so ur y value is 1....and ur ordered pair is (1,1) <==
