Option 1 =603 is the answer
We know that the area of a circle is represented by the equation:
And we know that the diameter of a circle is twice the radius:
So if we know that the diameter is 13m, we can solve for the radius:
-->
Then we can plug in this radius into the equation for the area of a circle, using 3.14 to approximate the value of pi:
So now we know that the area of the circle is 132.665 square meters.
Step-by-step explanation:
(4x + y)² - 2z = 16x² + 8xy + y² - 2z
substituting x = 4, y = -2 and z = 6,
= 16(4)² + 8(4)(-2) + (-2)² - 2(6)
= 16(16) + 8(-8) + 4 - 12
= 256 - 64 - 8
= 184
=
Answer:
42 hours
Step-by-step explanation:
1 pound = 3,500
3,500 × 3 = 10,500
1 hour = 250
10,500 ÷ 250 = 42
42 hours
When we have to divide fractions, we multiply the first one by the second one's reciprocal.
2/5 divided by 1/8
2/5x8/1
16/5
This is the simplest form of it. If you want to solve further the answer will be in decimals.
Hope it helped!
