Answer:
<h3>The answer is option B</h3>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius of the circle
From the question
Area = 154cm²
To find the radius substitute this value into the above formula and solve for the radius
That's
154 = πr²
Divide both sides by π
We have
Find the square root of both sides
Thats
r = 7.0014086
We have the final answer as
radius = 7.0 cm
Hope this helps you
Answer:
28
Step-by-step explanation:
Let x be the missing segment
We will use the proportionality property to find x
24/16 = 42/x
Simplify 24/16
24/16= (4×6)/(4×4)= 4/6 = 3/2
So 3/2 = 42/x
3x = 42×2
3x = 84
x = 84/3
x= 28
Answer/Step-by-step explanation:
=> any combination of numbers were formed or grouped when adding. The associative property of addition was applied.
=> the sum of two terms (addend) are multiplied by by a number separately (I.e., a(b + c) = a(b) + a(c) = ab + ac). The property applied is distributive property.
=> the numbers were grouped in any combination to arrive at same result when multiplying. Associative property of multiplication was applied.
=> the numbers where ordered in any manner to arrive at same result when multiplying. Cummutative property of multiplication was applied.
=> the order in which the nnumbers in the were arranged doesn't matter, as same result is arrive at. This is Cummutative property of addition.
Answer:
7
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the opposite interior angles
18x+9 = 5x-5 + 105
Combine like terms
18x+9 = 5x +100
Subtract 5x from each side
18x-5x +9 = 5x+100-5x
13x +9 = 100
Subtract 9 from each side
13x +9-9=100-9
13x= 91
Divide by 13
13x/13 = 91/13
x = 7
Answer:
13.0 cm
Step-by-step explanation:
We proceed by Pythagorean Theorem:
We are given a = 1 and b = 13
c ≈ 13.0
This is the answer rounded to the nearest tenth.
