Answer:
11.31
Step-by-step explanation:
<h3>given:</h3>
The diameter of the circle is 3.6 units.
<h3>to find:</h3>
Value of "a"
<h3>steps</h3>
Circumference of a circle in terms of radius:
Circumference = 2 · π · r = 2 · 3.14 · 1.8 = 11.31 (*)
In terms of diameter:
Circumference = π · d = 3.14 · 3.6 = 11.3 (*)
In terms of area:
Circumference C = √4·π·A = √4·π·10.18 = 11.31 (*)
Answer:
$5
Step-by-step explanation:
Given data
We are given that
Large lemonade= $6
Small lemonade= $4
Total amount = 6+4= $10
He keeps 50% of the total
= 50/100*10
=0.5*10
= $5
Hence he will keep $5
10. ? = 35
14. x = 1/2
18. 100 mm = 10 cm.
Answer:
y = 2, x = -1
Step-by-step explanation:
2y - 5x = 9
2y = 9+5x
y = (9+5x) /2
4y + 3x = 5
4((9+5x) /2) + 3x = 5
13x + 18 = 5
13x = -13
x = -1
y = (9+5x) /2
y = (9+5(-1)) /2
y = 2
