Answer:
12.57cm
Step-by-step explanation:
Formula : Pi×r²
pi×2²=4pi=12.56637061
rounded : 12.57cm
SinA = O/H
= 8<span>√3 / 16
=</span>√3 / 2
answer is B √3 / 2
Hey there!
In this picture, we have many pairs of adjacent angles:
1 and 2
2 and 4
4 and 3
3 and 1
This is because these pairs are being connected by a vertex and a side.
Hope it helps and have a great day!!!
X= — 1
—
15
This may be the answer
The sum of the numbers should total to 1. Let us say that
x is the missing number, therefore:
x + ¼ + ¼ + 1/5 = 1
x = 1 – ¼ - ¼ - 1/5
The numbers should have similar denominator:
x = 20/20 – 5/20 – 5/20 – 4/20
x = 6/20
<span>x = 3/10</span>
