The figure given in the question can be divided into two figure

A rectangle of 8 * 13 inch

and a triangle of 8 * 6 inch

The area of a rectangle is given by

Length * Breadth

8 * 13

= 104 sq.inch

The area of the triangle is given by

(1/2) * base * height

= (1/2) * 8 * 6

= 24 sq.inch

Total area = 104+24 = 128 sq.in

Therefore Option C is the right answer.

5. Brianna earns $19,500 per year. Lisa earns $1,000 per month. Write a numerical expression that represents how much more Brian
Morgarella [4.7K]

Answer:

19,500 - (1,000 x 12) = X

Brianna earns $ 7,500 more than Lisa per year.

Step-by-step explanation:

Given that Brianna earns $ 19,500 per year and Lisa earns $ 1,000 per month, to write a numerical expression that represents how much more Brianna earns per year than Lisa the following calculations and equations must be performed:

19,500 - (1,000 x 12) = X

19,500 - 12,000 = X

7,500 = X

Thus, Brianna earns $ 7,500 more than Lisa throughout the year.

Find the area of a circle with a circumference of 6.28 units
viktelen [127]

Answer:

area of the circle = 3.14 square units

Step-by-step explanation:

Circumference of the circle formula is 2\pir

where r is the radius of the circle

given circumference = 6.28

2\pir = 6.28

Value of pi is 3.14

2*3.14 * r= 6.28

6.28 r = 6.28

divide by 6.28 on both sides

r = 1

radius = 1

Area of the circle = \pi r^2

= 3.14 *1*1 = 3.14
