I'm assuming division, no?
So I'm going to multiply 28 by 3 to get 84. Than add 3 to 84 to get 87.
87 / 3 = 28 with a remainder of 3
Answer:
x=81
Step-by-step explanation:
Hey There!
So remember the triangle angle rule
all of the angles in a triangle add up to 180
so to find x we subtract the given angles (47 and 52) from 180
180-47=52=81
so we can conclude that x=81
X/2 x .09 =y
x/2 x .11= z
y + z = 420
((x/2) x .09) + ((x/2) x .11) = 420
.09x/2 + .11x/2 = 420
.2x/2= 420
.1x=420
x=4200
Plug that value back into the originals to check
4200/2 x .09 = 189
4200/2 x .11 = 231
-------
420

The volume of a sphere is given by the equation
, where r is the radius.
We are given the diameter of the sphere, but recall that the diameter is twice the radius:
. So the radius is half of the diameter:
.
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for <span>π.</span>
Answer:
80 inches
Step-by-step explanation:
Your pretty much finding the area so you would multiply 8 x 10
