Answer:
radius r = 2.38732415 m
diameter d = 4.77464829 m
circumference C = 15 m
area A = 17.9049311 m2
0.1(71x+33)
the soultion is
Answer:
We have
sale price + 6% x sale price = $121.37;
Then
(106/100) x sale price = $121.37;
sale price = $121.37 x 100 / 106;
sale price = $12137 / 106;
sale price = $114.50;
Step-by-step explanation:
Answer:
<u>417.4ft^2</u>
Step-by-step explanation:
Surface area of a cone = πr(r+√r²+h²)
r is the radius
h is the height
Substitute
Surface area of a cone = π(5)(5+√5²+21²)
Surface area of a cone = πr(5+√25+441)
Surface area of a cone = π(5)(5+21.59)
Surface area of a cone = 3.14*5*26.59
Surface area of a cone <u>= 417.4ft^2</u>
<u>Hence the surface area of the cone is 417.4ft^2</u>
