If l an m are parallel. Find the value of x and y

Svetllana [295]

(8y + 17) = (6x - 7)

(3x -29) + (6x -7) = 180
9x -36 = 180
9x = 216
x = 24

(8y + 17) = (6x - 7)
8y + 17 = 6(24) - 7
8y + 17 = 144 -7
8y = 120
y = 15

I hope this helps!! (and hope it’s correct hahah :))

The diameter is a circle is 16in. Find it’s circumference in terms of π. C= ________in

DIA [1.3K]

According to the question,

Diameter of circle = 16 in

We are asked to calculate it’s circumference in terms of π.

★ Circumference of circle = 2πr

___________________________________

Let us first calculate the radius of the circle.

→ Diameter = 2 × Radius

→ 16 in = 2r

→ r = 16 in ÷ 2

→ r = 8 in

___________________________________

Substituting values in the formula of circumference,

→ C = 2πr

→ C = (2 × π × 8) in

→ C = 16π in

Therefore, 16π inches is the required answer.
