Answer:
2.29 rads
Step-by-step explanation:
The length of the arc of a circle of radius r is given by;
l = rθ ---------------------------(i)
Where;
l = length of the arc
θ = central angle o that intercepts that arc and measured in radians.
From the question:
l = 16ft
r = 7ft
Substitute these values into equation (i) as follows;
16 = 7θ
Make θ subject of the formula
θ = 
θ = 2.29
Therefore, the radian measure of the central angle is 2.29 rads

Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation. You'll probably start out by just solving proportions, like this: Find the unknown value in the proportion: 2 : x = 3 : 9.
Now let's do it
2. 2 is not shown in the picture
3. 2 1/2 sugar/7 1/2 flour = x sugar/1 flour
cross multiply: 2 1/2/7 1/2 = x/1
7 1/2x = 1(2 1/2) ... 15/2x = 5/2 ... x=5/2×2/15= 1/3
answer: 1/3 cup sugar = 1 cup flour ... 1/3s:1f
5. 1 1/3p/3 1/3c = ₩p/1c
cross multiply: (1 1/3)/(3 1/3) = ₩/1
3 1/3₩= 1(1 1/3) ... 10/3₩=4/3 ... ₩=4/3×3/10
₩=4/10=2/5 qt papaya
2/5 qt papaya = 1 qt carrot ... 2/5p:1c
Answer:
The heigh of the triangle is 10cm
Step-by-step explanation:
The area of a triangle is given by the formula A=1/2bh where
A = the area of the triangle,
b = the length of the base, and
h = the height of the triangle.
To find the height when
the
Area of the triangle, A =45cm2,
base of the triangle, = 9 cm long.
Using the formula, A = 1/2 × b × h
45 = 1/2 × 9 × h
Cross multiplying
2×45 = 1×9×h
90 = 9h
h = 90/9 = 10cm
