Answer:
A. 8.09 × 10^-5
Step-by-step explanation:
4.1 x 10^-6 = 0.0000041
0.000085 - 0.0000041 = 0.0000809
0.0000809 = 8.09 x 10^-5
5.269 as a mixed number is, 5 269/1000
Answer:8000 i think
Step-by-step explanation:
=20 to the power of nine-20 to the power of four=20 to the power of three.
20 to the power of three is 8000.
Hope this helps.
Answer:
add all the sides that you have and subtract it from 180
Step-by-step explanation:
Answer:r = 2.81 centimeters
Step-by-step explanation:
The area of this circle can be found using the formula
A=πr^2
Where r = radius of the circle
π is a constant whose value is 3.14
We are given the area of the circle to be 25 square centimeters. To determine the length of the radius of the circle , we will make r the subject of the formula
r^2 = A/π
Taking square root of both sides of the equation,
r = √A/π
Since A = 25 and π = 3.14,
r= √25/3.14
r = 2.82166323992
Approximating to the nearest tenth of a centimeter,
r = 2.81 centimeters
