Answer:
4.46
Step-by-step explanation:
As the circumference of a circle is pi multiplied by the diameter to work out the radius you would first divide the circumference of 28 by pi, which gives you 8.92. This is the diameter, however the question is asking for the radius. To work out the radius you would divide the diameter by 2, which gives you 4.46. This is because the radius is half of the diameter.
1) Divide 28 by pi.
2) Divide 8.92 by 2.
Answer:
15(2d+1)
Step-by-step explanation:
we are going to multiply the numbers
5 x 6d + 5 x 3
30d + 5 x 3
30d + 15
then we factor out 15 from the expression
15 (2d+1)
-- there is an equation to find this: (2n + 1) + (2n + 3) = (whatever number is given as their sum)
use the equation: 2n + 1 is an odd interger, 2n + 3 is the next odd integer.
(2n + 1) + (2n + 3) = 88
add like terms.
4n + 4 = 88
4n = 84
n = 21
now plugin.
2(21) + 1
42 + 1
= 43 (the first odd integer)
this means the second one would be 45.
answer: 43 and 45
add them to check:
43 + 45 = 88

Answer:
x = 6
Step-by-step explanation:
(3√2)² = 18
using the Pythagorean theorem:
x² = 18 + 18 = 36
x = √36 = 6
