The answer is C. 89 in^2
This is found by (1/2(

))+70
r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5
You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.
Hope this helps!
Let the Length be L and the Width be W
The area is 8 cm²
LW = 8
The perimeter is 12
2(L + W) = 12
L + W = 6
Solve L and W:
LW = 8 --------------- (1)
L + W = 6------------ (2)
Equation (2):
L + W = 6
L = 6 - W -------------- Sub into (1)
(6 - W) W = 8
6W - W² = 8
W² - 6W + 8 =0
(W -2 )(W - 4) = 0
W = 2 or 4
When W =2, L = 6 - 2 = 4
When W = 4, L = 6 - 4 = 2
Answer: The Width is 2 cm and the Length is 4 cm
The answer is :
5 , 10 ,15 , 20 , 25, 30 ,35, 40 , 45 , 50 , 55, 60
Answer:
Theorem.
Step-by-step explanation:
Postulate/Axiom: Can't be proven or disproven.
Definition: Defines a term. Can be proven.
Theorem: Can be proven.
"Proof" (informal but it works): Triangle has 180°, that means two angles will be less than 180°. Right angles are 90°, that means two 90° angles add up to 180°. Something that is less than 180° is less than 180°.
This statement is provable, but doesn't necessarily define anything.
Answer:40%
Step-by-step explanation:
For every 5 cars two are red. Percentage of red cars to blue is 2/5 * 100 = 40%
