Answer:
The answer is 777.54418
Step-by-step explanation:
A= 2π r h + 2 π r 2 = 2 ·π · 5.5 ·17 + 2· π · 5.5 2 ≈ 777.54418
You must divide the 11 by 2 because that is the diameter and not the radius.
Answer:
7
Step-by-step explanation:
Because 6+6.25=12.25 48.25-12.25=36 6x6=36 6+1=7
Answer:
21/4
Step-by-step explanation:
7 + 3²(12-8)
=> 7 + 9(4)
=> 7 + 36
=> 42
Equation:-
42 / (2x4)
=> 42/8
=> 21/4

➷ Just work with what is inside the parenthesis
Also, move around the terms to help it make more sense:
(cosA cosB - cosA cosB + sinA sinB + sinA sinB)
As you can see, the 'cosA cosB' would cancel out through subtraction.
Now we have this:
(sinA sinB + sinA sinB)
This is just two sets of sinA sinB so it can be written as:
(2 * sinA sinB)
Simply place the values outside the parenthesis back there to get the answer
SinA sinB = 1/2 * (2 * sinA sinB)

Answer:
12 centimeters
Step-by-step explanation:
The side lengths of the triangle are: 26, 28, and 30 centimeters
a = 26 cm, b = 28 cm, c = 30 cm
To find the area, we first must find the semi-perimeter with the following equation:
s = (a+b+c)/2
= (28+26+30)/2
= 42 centimeters
Now, to find the area, we can use Heron's formula:
A =
336 squared centimeters
Since the area of the parallelogram is equal to the area of our triangle:
Area of Parallelogram = Area of Triangle
base ⋅ height = 336 squared centimeters
28 ⋅ height = 336 squared centimeters
height = 336/28
height = <u>12 centimeters</u>
