Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b =
= 60
Answer: 397
Step-by-step explanation:
8x8=64
3x3=9
18x18=324
324+64+9= 397
Total area of the circle is 1.12π square inches.
<h3>What is Area of circle?</h3>
The Area of circle is π times the square of the radius.
i.e., A = πr²
Given:
Area of one circle = 0.56π
As the second circle is also identical then the area will be same.
So, the total area of circle is
=2* 0.56π
=1.12π square inches.

Answer:
B) { 51, 149, 140 }
C) { 16, 63, 65 }
Step-by-step explanation:
We need to choose Pythagoras theorem formula

now, we can verify each options
option-A:
a=1
b=1
c=1
now, we can verify formula


We can see that left side is not equal to right side
so, this is FALSE
option-B
a=51
b=140
c=149
now, we can verify formula


We can see that left side is equal to right side
so, this is TRUE
option-C
a=16
b=63
c=65
now, we can verify formula


We can see that left side is equal to right side
so, this is TRUE
option-D:
a=6
b=8
c=11
now, we can verify formula


We can see that left side is not equal to right side
so, this is FALSE
Step 1: Locate and underline the tenth place (4) and look to the right (8)
1.48
Step 2: In this case, the digit to the right 8 is 5 or above. So, we add 1 to the tenth place 4. The digit at the right 8 becomes 0, thus we get 1.5 as the answer.
In short: 1.48 rounded to the nearest tenth is 1.5.
Hope that helped
