HELP PLZ I DONT GET THIS AGT ALL I SUCK AT MATH :( I REALLY NEED HELP CAN SOMEONE HELP PLZ

£94

Step-by-step explanation:

Basically, we want to find the surface area of this cylinder.

The surface area of a cylinder is denoted by: A = 2πr² + 2πrh, where r is the radius and h is the height. However, note that the farmer only wants to paint the curved surface of the cylinder, so we don't want to include the 2πr² part that accounts for the two circular bases. Instead, we actually just want to find the value of 2πrh.

Here, we see that the diameter is 8 metres, so since the radius is half the diameter, we know that r = 8/2 = 4 metres.

We also see that the height is 6 metres, so h = 6.

Plug these numbers in:

2πrh

2π * 4 * 6 = 48π ≈ 150.8 m²

We see that each can of paint will cover 20 m², so divide 150.8 by 20 to find the number of cans we need:

150.8 ÷ 20 = 7.5 ≈ 8 cans

Each can costs £11.75, so multiply 8 by 11.75 to get the total cost:

11.75 * 8 = £94

The answer is £94.

the correct answer is 5 6 and 7

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
