I cant see anything so redo it
Answer:
4/23
Step-by-step explanation:
√106 is equal to approximately 10.29563
Rounded of to 10.3
Ok, so what you would have to do is plug in all the variables you have provided into the equation. so you should get the equation:
2 (3.14)(2squared)+2 (3.14)(2)(4) <- you get the 4 from multiplying the radius by 2, which will give you the diameter, but it will also give you the height. So just do the math from there. So by putting it into my calculator, I got 74.72.
#1 (15)
50%= 1/2
1/2 of 30 is the same as 30÷2=15
#2 (20kg)
25%= 1/4
1/4 of 80 is the same as 80÷4= 20
#3 (30cm)
1/3 of 90 is the same as 90÷3=30
#4 (8m)
2/3 of 12 is the same as 12÷3= x2
12÷3= 4(2)= 8
#5 (70)
10% = 1/10
1/10 of 700 is the same as 700÷10= 70
#6 (280)
40%= 4/10
700÷10=x(4)
70(4)=280
#7 (2700 m)
9/10
3000÷10=x(9)
300(9)= 2700
