Question 1: The areas are equal
Question 2: The area of the circle would be 28.26 cm 2
inessss [21]2 years ago
3 0

Answer: #1) 3. The semicircle has twice the area of the circle

#2) 3. 28.26 cm

Step-by-step explanation:

#1) The formula for area of circle is A=πr².

First, plugging in the radius for the circle, A=π(5)², we get an area of about 78.54 inches².

Plugging in the radius for the semicircle, A=π(10)², which is equal to 314.159.... However, since it is a SEMI-circle, we will divide this value by 2 to give us an area of about 157.08 inches².

Comparing the two areas, we see the semicircle has twice the area of the circle as 78.54 x 2 = 157.08.

#2) Again use the area of circle formula, A=πr². The radius is half the diameter, so half of 6cm=3cm, meaning r=3. plug it in.

A= π(3)²

A= 28.27 cm²

What is the slope of the line threw (-7,-2) and (-6,7)
miv72 [106K]

Answer:

9

Step-by-step explanation:

To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

m=\frac{y_2-y_1}{x_2-x_1}

Here the points are (-7,-2) and (-6,7). Substitute and simplify.

m=\frac{7--2}{-6--7}=\frac{7+2}{-6+7}=\frac{9}{1}=9

HELP ASAP PLEASE ILL GIVE BRAINIEST!!! <br> I’m stuck !!!!
rosijanka [135]

Answer:

Therefore the value of EC is 13 unit.

Step-by-step explanation:

Given:

ABCD is a Rectangle

EC = 6x + 1

AE = x +11

To Find:

EC = ?

Solution:

ABCD is a Rectangle .........Given

Diagonal of Rectangle Bisect each other. .......Property of Rectangle

AE = EC

Substituting the values we get'

x+11=6x+1\\6x-x=11-1\\5x=10\\x=\dfrac{10}{2}\\\\x=2

Substituting 'x' in EC we get

EC=6\times 2+1=13\\EC=13\ unit

Therefore the value of EC is 13 unit.

What is the area of this trapezoid?
liberstina [14]

Answer:

7.5\:\text{square units}

Step-by-step explanation:

The area of a trapezoid is given by the average of the bases multiplied by the height.

What we're given:

  • Height of 3
  • Bases of 1 and 4

The average of the bases 1 and 4 is equal to \frac{4+1}{2}=\frac{5}{2}=2.5

Therefore, the area of the trapezoid is 2.5\cdot 3=\boxed{7.5\:\text{square units}}

3p − 5 = 10

Add 5 to each side

3p-5+5 =10+5

3p = 15

Divide each side by 3

3p/3 = 15/3

p =5

Dave is three times older than Jim, and Jim is half Bill’s age. If their average age is 64, what is Jim’s age?
Tema [17]
<h3><u>Dave is 96 years old.</u></h3><h3><u>Jim is 32 years old.</u></h3><h3><u>Bill is 64 years old.</u></h3>

d = 3j

j = 1/2b

64 = (d + j + b)/3

d = 3(1/2b)

d = 1.5b


64 = (1.5b + 1/2b + b)/3

Combine like terms.

64 = (3b)/3

Multiply both sides by 3.

192 = 3b

Divide both sides by 3.

64 = b

Because we have the value for b we can plug it into the other equations to solve for the other ages.

j = 1/2b

j = 1/2(64)

j = 32


d = 3j

d = 3(32)

d = 96
