Hey there! :)
The formula for finding volume of a sphere = 4/3 · π · r³
Radius = 1
1³ = 1 × 1 × 1 = 1
π = 3
3 × 1 = 3
3 × 4/3 = 12/3 = 4
The volume is 4 in³
Hope this helps :)

2:3
Answer: 2:3
<h3>
Answer: 48 degrees</h3>
=============================================
Work Shown:
Apply the law of cosines
a^2 = b^2 + c^2 - 2*b*c*cos(A)
10^2 = 13^2 + 11^2 - 2*13*11*cos(A)
100 = 290 - 286*cos(A)
100-290 = -286*cos(A)
-190 = -286*cos(A)
190 = 286*cos(A)
286*cos(A) = 190
cos(A) = 190/286
A = arccos(190/286)
A = 48.368620460647
A = 48
Make sure your calculator is in degree mode.
Answer:
9, 12
Step-by-step explanation:
Just multiply the 3,4,5 triple by 3 and u get 9, 12, 15
37.5*0.010=.375 (or press % button on calculator)
80*.375=30
