Answer:
30/95
Step-by-step explanation:
because 95 cant be split
r = 30 cm
formula: A = πr²
A = πr²
A = π30²
A = 900π
if π = 3.14, then the answer is 2,826 cm
if π is not defined, the answer is 2,827.43 cm
Answer:
Step-by-step explanation:
We have:
$log_{10} (10)=1$
$\therefore \log_{10}(2\times 5)=1$
$\implies \log_{10}(2)+ \log_{10}(5)=1$
$\implies \log_{10}(5)=1-\log_{10}(2)$
$\implies \log_{10}(5)=1-0.3010=\boxed{0.6990}$
