Answer:
The value of y s 2.5
Step-by-step explanation:
Vertical angles are always equal to one another. In this case, we can find the angles by setting the two values equal and solving algebraically.
2y + 5 = 4y
5 = 2y
2.5 = y
Answer:
The area of the circle is 314mm²
Step-by-step explanation:
To solve this problem we have to use the formula for calculating the area of a circle
a = area
π = 3.14
r = radius
d = diameter
r = d/2
r = 20mm / 2
r = 10mm
a = π * r²
we replace the known values
a = 3.14 * (10mm)²
a = 3.14 * 100mm²
a = 314mm²
The area of the circle is 314mm²
