The area of a circle:
r - the radius, which is equal to half the diameter d
The first circle:
The second circle:
the second circle has a diameter that is four times the diameter of the first circle.
The ratio of the area of the smaller cirlce to the area of the larger circle:
The ratio is 1:16.
Answer:
c
Step-by-step explanation:
Answer:
a) 301.6 cm³
b) 188.5 cm²
Step-by-step explanation:
The volume and lateral surface area of the cone can be found using the given dimensions with the given formulas. All that is needed is to substitute the appropriate values and do the arithmetic.
__
<h3>a) volume</h3>
The volume is given by the formula ...
V = 1/3πr²h
The dimensions are given on the diagram: r = 6 cm, h = 8 cm. Using these values in the formula, we find the volume to be ...
V = 1/3π(6 cm)²(8 cm) = 96π cm³ ≈ 301.6 cm³
The volume of the cone is about 301.6 cm³.
__
<h3>b) area</h3>
The lateral area of the cone is given by the formula ...
A = πrl
The dimensions are given on the diagram: r = 6 cm, l = 10 cm (the slant height). Using these values in the formula, we find the area to be ...
A = π(6 cm)(10 cm) = 60π cm² ≈ 188.5 cm²
The area of the curved surface is about 188.5 cm².
Okay well you told me that there are 8 1 quart containers but not how much punch there really is. so depending if Joanne made more than 8 quarts of punch, she would have more punch than what she can fit into her fridge. if she has made less then she is all good
