Answer:

27.0 feet

Step-by-step explanation:

Length of an arc (s) = 2πrθ/360................. Equation 1

Where r = radius of the circle, θ = angle in degree substends by the arc at the center of the circle.

From the question,

Given: r = 9 feet, θ = 3 radian = 3 (57.2950) = 171.89°

Constant: π = 3.14

Substitute these values into equation 1

s = 2(3.14)(9)(171.89)/360

s = 9715.2228/360

s = 26.99 feet

s ≈ 27.0 feet

padma mixes 300ml of her favourite drink.she uses 15% orange juice and 5% pineapple juice.the rest is lemonade. how many ml of l

mestny [16]

Percentage of Lemonade = 100 - (15 + 5)
= 100 - 20 = 80%

Now, We have to calculate the 80% of total amount of the drink i.e., 300 ml

So, 300 * 80%
= 300 * 0.80 [ 80% = 0.80 ]
= 240

In short, Your Answer would be: 240 ml

Hope this helps!

Find the area of the figure. Round to the nearest tenth if necessary.

Anestetic [448]

So I went ahead and divided up the figure so that you would understand what I'm going to tell you. Let's start with the red rectangle.

The distance from point R to point I is 6 units and the distance from Point R to point S is 5 units. 6*5 = 30 so that red rectangle has an area of 30 units

Now let's calculate triangle AVI. Area of a triangle is Base * Height. The base is 1 and the height is 5 which means the area of triangle AVI is 5.

Next, triangle ALT. From Point A to point L is 4 unit. From Point L to point T is 3 units. 4*3 is 12. So triangle ALT has an area of 12.

Triangle TSI. From Point T to point L is 3 units. From Point L to X is 2. Triangle TSI has an area of 6.

Now we add all of them up. 30+5+12+6 = 53. In total, RSTUV has an area of 53
