The base's length is 8 and it's width is 7, so it's perimeter will be

. To find the lateral area you shoul multiply this with it's height. So,

(h is height).
Answer:
58
Step-by-step explanation:
follow the pattern. The pattern is to take away 10, for each subsequent number.
B. Total number of times the activity is performed: Number of times an event occurs
Area of square = 10x10
= 100
area of circle = pi(r)^2
= pi (5)^2
=25pi
area of shaded = 100 -25pi
circumference of circle = 2pi (r)
= 2pi(5)
= 10pi
perimeters of shaded = 10pi + 10 + 10
= 10pi +20
The answer of f(-2) is 42
