Answer:
Step-by-step explanation:
I take it that what you mean is
10/4 + 12/6 + 17/12
Change all the questions so that their denominators are 12
10*3 / 4*3 + 12*2 / 6*2 + 17/12
30 / 12 + 24/12 + 17/12
(30 + 24 + 17)/12
71 / 12
5 11/12
5.917
I think it’s A. 12mm Bc if u take away 4mm from the 10mm it gives u the triangles base which is 6mm and then taking away 8mm from 12mm gives u 4mm which would be the height
To find the area of a triangle u need the base and height
Triangle Area= 1/2bh
1/2(4)(6)= 12

Step-by-step explanation:
find area of 1 small bubble
πr² = π × 5²
= 78.54
total area of 4 small bubble
78.54 × 4 = 314.16
total area of 4 small bubble = area of big bubble
= 314.16
find it's radius
πr² = 314.16
r² = 314.16 ÷ π
r² = 100
r = √100
r = 10
