Area of a circle = pi • r^2
We need to isolate for r.
A/pi = r^2
r = sqrt(A/pi)
r = sqrt(30.8/pi)
r = 3.1311251164
Diameter = 2r
Diameter = 6.26225023
Diameter = 6.3 m
Answer:
7×10^(-2)×8×10^5 = 56000
convert to scientific notation = 5.6 × 10^4
(scientific notation)
= 5.6e4
(scientific e notation)
= 56 × 10^3
(engineering notation)
(thousand; prefix kilo- (k))
= 56000
(real number)
Step-by-step explanation:
Answer:
C. 5
Step-by-step explanation:
a triangle has 180 degrees as shown 1 angle has 88 degrees and the other 2 angles are equal basically divide 92 by 2 and you would get 46 then do that reverse thingy subtract the 1 and get 45 the divide 45 by 9 and get 5
Its C.
Okay! In order to find 8 groups of .32 you'd simply divide them. So:
[.32 ÷ 8] = .04
To check you multiply:
[8 x .04] = .32.
The answer is .04
