Answer:
She can make 2 2/5 necklace in one hour
Step-by-step explanation:
60/15=4 so she makes 3/5*4=12/5=2 2/5
Answer:
The diameter was
in.
Step-by-step explanation:
The arc of a circle is given by

where
s = arc length
r = radius of the circle
θ = measure of the central angle in radians.
From the information given
s = 4 in
θ = 32º
To find the diameter of the original pizza, we use the formula of the diameter of a circle

First, we need to convert the angle to radians

Next, solve for r from the arc formula

Then, we use the diameter of a circle formula

If a triangle has sides of 7 cm and it is an equilateral you can draw a line right down the middle to form two congruent triangles.
These smaller triangles have a hypotenuse of 7cm and a base of 3.5 cm (7/2)
To work out the height, use Pythagoras’ theorem.
a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the other two sides
7^2 - 3.5^2 = 36.75
Square root answer
= 6.06 cm
That’s the height of the triangle
Area of a triangle is base x height divided by 2
So 7 x 6.06 = 42.43…
/2
= 21.2 cm^2 to one d.p
