Answer:
Step-by-step explanation:
cross multiply
57(QR)=926.9
QR=16.26...
round to nearest tenth
QR=16.3
(12)(3)(-2)
4/3, -3
30 mm, 2.5cm,20cm and 1m
Volume of sphere = 4/3 x PI x r^3
= 4/3 x 3.14 x 6^3
= 904.3 cubic meters
Volume of cone = PI x r^2 x h/3
h = √13^2-5^2 = 12
= 3.14 x 5^2 x 12/3
= 314 cubic meters
