Answer:
929.409square feet
Step-by-step explanation:
Formula 4πR²
(4×π×8.6²)ft
929.4087706ft square
To hundredths it will be equal to two decimal places ie 929.408square feet
Answer:
14.4cm
Step-by-step explanation:
Let the 7th length be y
Mean of the length = sum of all the length/number of let
Mean of the length = 13cm
13 = (11.8 + 12.4 + 12.5 + 13.2 + 13.6 + 13.1 + y) /7
13 = (76.6 + y) /7
Cross multiply to express in linear form
13 x 7 = 76.6 + y
91 = 76.6 + y
Collect like terms
91 — 76.6 = y
y = 14.4cm
Therefore, the 7th length is 14.4cm
Answer:
y = -40
Step-by-step explanation:
y/-4 + 5 = 15
y/-4 = 10
y = -40
Answer:
