Answer:

A = 201 cm²

Step-by-step explanation:

We know that the area of a circle can be calculated with the formula:

A = πr² = π(d/2)²

with d being the diameter.

Therefore:

A = 3.14(8cm)² = 201 cm²

Diameter =16
Radius = half of 16=8
Formula is pi*r2
3.14*64=200.96

Describe how to find the number of four dollar train ticket you can buy with $32

aleksley [76]

You solve this, you simply divide 32 by 4 to find out how many you can buy. If you divide 32 by 4, you get 8. So you can buy 8 train tickets in total.

Find the measure of angle N. A. 150° B. 8° C . 90° D. 294°

oee [108]

Answer:

$\angle N=150\degree$

Step-by-step explanation:

The sum of interior angles of a 5-sided polygon is 540 degrees.

We sum all the angles to get:

<M+<L+<N+<O+<P=540

90+90+(17x+4)+(18x+6)+(10x-10)=540

45x+180=540

45x=540-180

45x=360

x=8

N=18*8+6

$\angle N=150\degree$
