Find the measure of the indicated angle. Round to the nearest tenth.

Step-by-step explanation:

cos θ=12/16=3/4=0.75

θ=cos^{-1}(0.75)≈41.4°

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
