Use the Pythagorean theorem. The Pythagorean Theorem uses the following formula:
Plug in the known values into the equation:
Subtract both sides by 36.
Square root both sides to get b by itself.
The value of x is 8.
16cm
Dividing 81.9 cm^2 by 4.9cm will give you about a 16 cm height.
:) Good Luck
Answer:
C.) 7.14 in²
Step-by-step explanation:
The figure is made up of a square and a circle. The circle is divided in half and each piece is set on one side of the square. This means that the diameter of the circle is equal to the length of the sides of the square, 2 inches.
The area of the square can be found by multiplying length times the width:
The area of the square is 4 inches, and since we multiplied two lengths, we square the value:
A=4in²
Now find the area of the circle using the formula:
The radius is half of the diameter, so the radius is 1. Insert values and solve:
The area of the circle is equal to π. Add the values together:
The area of the figure is 7.14 in²
:Done
Answer:
One solution
Step-by-step explanation:
As a generalization: an equation of degree n has n solutions. A quadratic equation has the second degree and thus two a solutions; a third degree equation has three, and so on. Thus, a first degree (linear) equation has one solution.
