How much longer is the big arc than the small arc. Give the answer to 1 decimal place
romanna [79]
Circumference of the outer circle = 2πr = 2π(6) = 12π

circumference of the outer arc = 120/360 x 12π = 12.57cm

circumference of the inner circle = 2πr = 2π(5) = 10π

circumference of the inner arc = 120/360 x 10π = 10.47 cm

Difference in length = 12.57 - 10.47 = 2.1cm (1 d.p.)

Answer: 2.1cm

An ice cream cone has a diameter of 7 cm and a height of 13 cm. How many milliliters of melted ice cream can it hold? (1 cm3 hol
allsm [11]
This question is asking for the volume of the cone.
The formula is 1/3π r²h where r is radius and h is height.
First we must find the radius by dividing the diameter in half, giving us 3.5
Now we plug our values into the formula like this:

1/3 π r²h
1/3 π3.5² 13

This gives us the answer of 166.76mL or 166.8mL depending on how you want to round it.

Hope this helps :)
