Answer: 34.57 inches.
Step-by-step explanation:
Given : Diameter of tree's trunk = 11 inches
Then, the length of ribbon needed just to reach around the tree = Circumference of trunk.
We know that the circumference of the circle is given by :-
, where d= diameter
Then, Circumference of trunk. = 
Put
, we get
Circumference of trunk. = 
Hence , the length of ribbon needed just to reach around the tree = 34.57 inches.
Answer:
a cylindrical carton of oatmeal with radius 3.5 in. is 9 in. tall. all cardboard, how much cardboard is used to make the oatmeal carton?
Step-by-step explanation:
x = 45°
Solution:
Given data:
Measure of larger arc = 152°
Measure of smaller arc = 62°
<em>If a tangent and a secant intersect at the exterior of a circle then the measure of angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>



⇒ x = 45°
The value of x is 45°.
Answer:
4.0
Step-by-step explanation:
Look at the decimal place next to the tenths place. It has a 2 in its place. The rule for rounding is that any number 4 or lower is rounded down. Any number 5 or above is rounded up. The number is 2, which is below 4, so we round down. The tenths place would stay the same because it can't get any smaller. Therefore, 4.028 is rounded down to 4.0
