Answer:

132.73

Step-by-step explanation:

the equation for area of a circle is A=πr*2

if your diameter is 13 simply take half of that and plug into the equation

π(6.5)*2 which when put into a calculator comes out to 132.732289

The answer is 132.665 rounded is 132.67

area= r2 × π
13÷ 2 = 6.5
6.5 × 6.5 = 42.25
42.25 × 3.4 = 132.665 ------> 133.67

Find the total surface area of the figure below:
kow [346]

Answer:

95

Step-by-step explanation:

Formula -

Triangle Area - 1/2bh

Square - l x w

Triangle - 5 x 7 = 35/2 = 17.5

Since there are four triangle, we will multiply 17.5 x 4 which is equal to 70

Square  - 5 x 5 = 25

Now we add both 70 and 25 which is 95

So the total surface area is 95

Evaluate 3x for x = −2, x = 1, and x = 3. Question 18 options: A) 1∕3, 0, 9 B) 1∕9, 3, 27 C) 9, 3, 27 D) 1∕9, 9, 27
icang [17]

Answer: B) 1/9, 3, 27

Step-by-step explanation:

Here, we need to evaluate 3^x for x = -2, x = 1, \text{ and } x = 3.

So, we substitute values of x in the given function.

At x= -2, we have

3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9}\ \ \ [\because\ a^{-n}=\dfrac{1}{a^n}]

At x= 1, we have

3^1=3

At x= 3

3^3=3\times3\times3=27

So, the values of  3^x for  

Thus, the correct answer is B) 1/9, 3, 27
