What is the surface area of the cone? Express your answer in terms of π.b
weeeeeb [17]

Given:

Radius of the cone = 5 ft

Slant height of the cone = 21 ft

To find:

The surface area of the cone

Solution:

Surface area of cone formula:

SA=\pi r^{2}+\pi r l

where r is the radius and l is the slant height.

SA=\pi \times 5^{2}+\pi \times 5 \times 21

SA=\pi \times 25+\pi \times 105

SA=25 \pi+ 105 \pi

SA=130 \pi

The surface area of the cone is 130π square feet.

The ticket price for an ice hockey match used to cost £19.60. The price has now increased by 12.5%. How much will 2 tickets cost
Amanda [17]

Answer:

The 2 tickets will cost £44.10 after the increase.

Step-by-step explanation:

First, you have to multiply £19.60 by 12.5% to find the increase in the cost of tickets.

19.60(0.125)=2.45

Add the price increase to the original cost to find the new cost of each ticket.

19.60+2.45=22.05

Multiply the result by 2 since you have to look for the cost of the 2 tickets.

22.05(2)=44.10
