Andy is buying a car

Oliga [24]

Answer:

£503.75 per month

Step-by-step explanation:

7% decrease on a £6,500 car

= 7% of 6,500

= 7/100 * 6,500

= 0.07 * 6500

= £455

Amount of the car = £6,500 - £455

= £6,045

he will pay the full balance in 12 equal month payments

Amount paid each month = £6,045/12 months

= £503.75 per month

Find the surface area of the cylinder in terms of pi.

Ilia_Sergeevich [38]

Hello!

To find the surface area of a cylinder you use the equation

$SA = 2 \pi rh+2 \pi r^{2}$

SA is surface area
r is radius
h is height

Put in the values you know

$SA = 2 \pi 9 * 3 + 2 \pi 9^{2}$

Square the number

$SA = 2 \pi 9 * 3 + 2 \pi 81$

Times the 9 and 3

$SA = 2 \pi 27 + 2 \pi 81$

Multiply the 2 and 27

$SA = 54 \pi + 2 \pi 81$

Multiply the 2 and 81

$SA = 54 \pi + 162 \pi$

Add

$SA = 216 \pi$

The answer is $216 \pi$

Hope this helps!
