Answer:
H = 2 S = 50 A = 50.2
Step-by-step explanation:
A=2πrh+2πr2
S = 2tr2 + 2trh
S = 2 (t x r) + (h x 2t) x r Try out ^2 for Radius
S = 2t x r^2 + r x h x 2t Rearrange back and cross out for square^2
S = 6t x 4 + 6t x r x h Cross out for t
S = 6 x 4 + 6 x 2 x h Balance out...
S= 24 + 12 x 2 Find h = 2
S = 36 + 24
S= 50 sq2
A = 50. 2
R = 2
H = 2

Answer:
23 stones are going to be needed
Step-by-step explanation:
Answer is A
if x+y=5
y= -x+5
2x + (-x+5) =-2
2x -x +5 = -2
x+5 = -2
x=-7
Answer: 5/4
Step-by-step explanation:
To get the number of groups of 4/5 are in 1, we divide 1 by 4/5. This will give:
= 1 ÷ 4/5
= 1 × 5/4
= 5/4
<h3>There are 5/4 groups of 4/5 in 1.</h3>
