Answer:
ten and a half
Step-by-step explanation:
2×3.5= 7
3×3.5= 10.5
So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)
Answer:
3/8 as a decimal is 0.375
Step-by-step explanation:
i√5
steps:
negative square root is called a complex number
for a negative square root standard form means have an i in the number
i = √-1
standard form for a complex number is
a+bi
√-5 = √5 x √-1
i√5
