Answer:
The general formula for the total surface area of a right prism is T. S. A. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.
Step-by-step explanation:
Whats the diameter?
1/8(3.14) = 0.3925
Step-by-step explanation:
The formula for calculating a circle's circumference is πd, where π is an irrational number (3.14....) and d is the diameter of the circle.
In the circle with diameter 19.5cm, the circumference is around 3.14 * 19.5cm = 61.23cm. (A)
B. 54 meters
first you want to set up your ratios and cross multiply to figure out the number to square l's ratio. which would be 10.8.
then use formula for perimeter
2(l)+2(w)=9
2(10.8)+2(18)=53.6-rounded =54<span />
Answer: X = 2
Step-by-step explanation:
Y & X
Y = KX
K = Y/X = 16/4 = 4
Y= 8
K =4
X=?
X = Y/K
X = 8/4 = 2
