1.- In this problem we have to find the area of the circle. We know that the formula to find the area of a circle is:
A= πr<span>² 
</span>Meaning area of the circle= 3.14*radius<span>² 
Since the radius is equivalent to half the diameter, and we know the diameter is 40, the radius is 40/2 or 20ft
Which means the area of this circle is equal to
3.14*20</span><span>²
Which is equal to 1256

2.- Here we need to find the radius
And since the diameter of the tablecloth is equal to 42+8, to find it we just need to divide 50 by 2 which gives us 25
50/2= 25

3.- This question asks for the area to obtain it we use the formula:
</span>A= πr² 
So...
Area= 3.14*25² 
Which is equal to 1962.5


ANSWERS:
1.- 1256 in² (option 2)
2.- 25''  (option 3)
3.- 1962.5 in² (option 3)

solniwko [45]

Answer:

m∠2 = 78°

Step-by-step explanation:

From the given picture,

lines 'm' and 'n' are the parallel lines and line 't' is the transverse line.

∠1 and angle with the measure of 78° are corresponding angles.

Therefore, m∠1 = 78°

m∠1 = m∠2 [Vertical angles are equal]

m∠2 = 78°

Could some please help and explain?
Sophie [7]

Answer:

x = 7

Step-by-step explanation:

A rhombus is a parallelogram where all sides are equal. Therefore, as we know two sides are equal to 7x+8 and 9x-6, we can say that

7x+8 = 9x - 6

subtract 7x from both sides to put the variable on one side

2x - 6 = 8

add 6 to both sides to isolate the variable and its coefficient

2x = 14

divide both sides by 2 to isolate x

x = 7
