The last answer choice
Answer:
11.78
Step-by-step:
78x + 8x + 12x + 20x + 28x
78x + 32x + 28x
= 138x
1626.35/138
= 11.78
First, find the radius of the circle. The radius of a circle is half the diameter. r=13/2=6.5
Second, use the equation A=pi * r^2 to find the area of the circle.
A=(3.14) * (6.5^2) = 132.665m^2
so the answer is 132.7 m^2.
Answer:
75 + 20 = 5 (15 + 4) = 5 × 19 = 95
Step-by-step explanation:
The prime factors of 75 are 3 × 5 × 5.
Again, the prime factors of 20 are 2 × 2 × 5
Therefore, the greatest common factor of 75 and 20 is 5.
Now, 75 + 20
= 5 × 15 + 5 × 4
= 5(15 + 4) {Using the distributive property of multiplication}
= 5 × 19
= 95 (Answer)
