Step-by-step explanation:
Given that,
The height of the cone, h = 24 cm
The radius of the cone, r = 10 cm
The slant height of the cone is :
The lateral area of the cone is given by :
The surface area of the cone is given by :
Answer: 8=201.06
4=50.27
Step-by-step explanation: What I mean by this is that if the radius (the distance from the center of the circle to the edge of the circle ) is 8 then the area of the circle is 201.06 and if the radius of the circle is 4 then the area of the circle is 50.27
Answer: £535
Step-by-step explanation:
Herr is the complete question:
Tim and three friends go on holiday together for a week.
The 4 friends will share the costs of the holiday equally,
Here are the costs of the holiday.
£1280 for 4 return plane tickets
£640 for the villa
£220 for hire of a car for the week
Work out how much Tim has to pay for his share of the costs.
Firstly, we have to calculate the total cost of the holiday. This will be:
= £1280 + £640 + £220
= £2140
We are also told that they will share the costs equally. Since there are 4 people, Tim will have to pay:
= £2140 ÷ 4
= £535
Tim will pay £535
Answer:
f(x) = f(-x) = x^2 -1 is an <u>even</u> function
Step-by-step explanation:
When f(x) = f(-x), the function is symmetrical about the y-axis. That is the definition of an <em>even</em> function.
___
An odd function is symmetrical about the origin: f(x) = -f(-x).
