Answer:
Grace should use her phone for 58 minutes to maintain an average of 55 minutes.
Step-by-step explanation:
Usage of first month = 43 minutes
Second month = 62 minutes
Third Minutes = 57 minutes
Let, the usage of fourth month = k minutes
Mean of the data = 5 minutes
Now, Average of a Data = 
⇒
or, 55 x 4 = 162 + k
⇒ 220 - 162 = k
or, k = 58 minutes
So, Grace should use her phone for 58 minutes to maintain an average of 55 minutes.
Answer:
<u>27π units²</u>
Step-by-step explanation:
The rest of the question is the attached figure.
This shape represents (3/4) of a full circle.
So, find the area of a full circle with radius 6 units, then multiply the result by 3/4 to obtain the area of the given shape.
Area of full circle = π r²
So, Area of full circle = π(6)² = 36π units²
Then the area of the given shape is = <u>(3/4)(36π) = 27π units²</u>
