Answer:
A = 16π cm²
Step-by-step explanation:
We require to find the radius r
Given circumference C = 8π , then
2πr = 8π ( divide both sides by 2π )
r = 4 , then
A = πr² = π × 4² = 16π cm²
The first one since the 5 has the radical symbol
Is it 0.2 repeating? I'm not sure sorry hon...
All triangle equal 180 degrees so add the 53 and 90 and it’s 90 because it’s a right triangle 53+90= 143 then subtract 143 from 190 so 190- 143= 47 so the missing degree is 47
