The radius of the base is 10 cm.
Solution:
Height of a cone = 15 cm
Volume of the cone = 1570 cm³
To find the radius of the base of the cone:
Volume of the cone = 
Divide by 15.7 on both side of the equation, we get
Taking square root on both sides of the equation, we get
⇒ r = 10
Hence the radius of the base is 10 cm.
Answer:
B) 81°
Step-by-step explanation:
∡1 ≅ ∡5 because they are corresponding angles
∡5 ≅ ∡7 because they are vertical angles
therefore, ∡1 ≅ ∡7
since the angles are equal we can create the following equation:
3x + 18 = 2x + 39
x + 18 = 39
x = 21
∡7 = 2(21) + 39
∡7 = 42 + 39
∡7 = 81
Answer:
175.5y
Step-by-step explanation:
9 (1.5) = 13.5
13.5 (13) = 175.5
175.5 (1y) = 175.5y
