Answer:
V = ⅓π(9²)(24) = 648π ft³ ≈ 2,035.75 ft³
Step-by-step explanation:
Answer: length of arc = 4.71 feet
Step-by-step explanation:
An arc is a portion of the circumference of a circle. The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 2 feet
θ = 135 degrees
Therefore,
Length of arc = 135/360 × 2 × 3.14 × 2 = 4.71 feet
520 x 0.2 = 104
520 + 104 = 625
Curtley's annual heating cost before he got his loft insulated was $624.00
You take 12 * 6 = 72, then divide by two. 72 / 2 = 36 in squared
