Brian pays £465.98 a year on his car insurance. The insurance company reduces the price by 3.6%.How much does the insurance cost
inysia [295]

Answer:

The correct answer is £449.20 rounded upto 2 DP.

Step-by-step explanation:

Brian pays £465.98 a year on his car insurance.

The insurance company reduces the price by 3.6%.

The amount reduced by the insurance company is 3.6% of 465.98 = £16.77528.

Price the insurance company charges now is given by subtracting the previous cost with the reduction amount.

Thus the insurance cost now = £ (465.98 - 16.77528) = £449.20472 ≈ £449.20.

Thus the reduced insurance cost Brian has to pay now is £449.20 rounded to 2DP.

2. Find the area and circumference of the circle to the right.<br>16.6 m<br>​
adoni [48]

Answer:

AREA:

A=216.42m^2

CIRCUMFERENCE:

C=52.15m

Step-by-step explanation:

The formula that is used to calculate the area of a circle is:

A=\pi r^2

Where "r" is the radius of the circle.

The formula for calculate the circumference of a circle is:

C=2\pi r

Where "r" is the radius of the circle.

Then, you need to find the radius. This is:

r=\frac{16.6m}{2}=8.3m

Substituting the radius, you get that the area and the circumference are:

AREA:

A=\pi (8.3m)^2=216.42m^2

CIRCUMFERENCE:

 C=2\pi (8.3m)=52.15m
