Answer:
1) 1/3
2) 4:1
Step-by-step explanation:
20 Bc 15x15=225 and 25x25=625 625-225=400 and 400 squared root is 20
Circumference of a circle
C = 2πr
since r = 14 then
C = 2π14
C =28π.
Area of a circle
A = πr²
A = π14²
A = 196π
Answer:
<h2>
3y + 2 = 8</h2>
Step-by-step explanation:
solve A
2y - 3 = 19
2y = 22
y = 11
solve B
3y + 2 = 8
3y = 6
<h2>
y = 2</h2>
solve C
4y - 4 = -4
4y = 0
y = 0
solve D
5y + 1 = 10
5y = 9
y = 9/5
