Answer:
=150.79644...cm²
~150cm²
Step-by-step explanation:
cylinder surface area = 2 pi r h + 2 pi r²
(4)x5 is the same as (4)5 or 4 x 5
it equals 20
Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,
5x - y = 1/4; this equation is written in slope - intercept form
Slope - Intercept form formula: y = mx + b
-Move '5x' to the left side of the equation
-Move 'y' to the right side of the equation
y = 5x - 1/4
