Answer:
x = 15m
Step-by-step explanation:
The second triangle (large) is 3 times greater than the first triangle (small).
6 x 3 = 18 4 x 3 = 12 5 x 3 = x
5 x 3 is 15, so x is 15m
The length of the minor arc AB is 6.3cm
Radius is half of the diameter so the radius of 4 is 2
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).
-129/13
Find x then subtract 9
