You'd move the decimal to the right twice so 0.0514 as a percentage is <span>5.14%</span>
Answer:
25.12 cm²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr²
where r is the radius. Here, the diameter is given as 8 cm, so the radius will be half that, or 4 cm. The area is then ...
A = 3.14(4 cm)² = 50.24 cm²
The green shaded part is 1/2 a circle, so is half this area:
shaded area = 25.12 cm²
Y=2x+4
y=2x-4
and the last one is already in standard form
Answer:
ummm it think so
Step-by-step explanation:
The area is when you muliply base×hight wich is 17×8.5=144.5 then divide by 2 so 144.5÷2=72.25
perimeter is when u add all sixes so its 17+8.5+19=44.5
P=44.5
