your answer would be
2/5, 3/7, 3/5, 1/2
Answer:
07
Step-by-step explanation:
3z - 7 = 14
3•7=21
21 - 7 = 14
Answer:
C = 24.5 in
Step-by-step explanation:
Formula to find the circumference of a circle is :
C = 2πr
Here,
r ⇒ radius
So let us solve now.
C = 2πr
C = 2 × π × r
C = 2 × 3.14 × 3.9
C = 24.492 in
So, they've asked for nearest 10th.
Therefore, the answer will be 24.5 in.
Hope this helps you :-)
Let me know if you have any other questions :-)
A)
Two sides are 8 x 2 = 16 x 2 = 32 sq. in.
Two sides are 11 x 2 = 22 x 2 = 44 sq. in.
Top is 8 x 11 = 88 sq. in.
Total surface area: 32 + 44 + 88 = 164 square inches.
B) Area of a circle = PI x r^2
Area = 63.585
63.585 = PI x r^2
Using 3.14 for PI:
63.585 = 3.14 x r^2
Divide both sides by 3.14:
r^2 = 63.585 / 3.14
r^2 = 20.25
r = √20.25
radius = 4.5 inches.
C)
Diameter = radius x 2
Diameter = 4.5 x 2 = 9 inches.
