Question

the height of a cone is represented by the symbol: a t b v c h d π which of the following formulas is used to calculate the area of the base of a cone? a π r ^ { 2 } h b π r ^ { 2 } c \frac { 4 } { 3 } π r ^ { 3 } d \frac { 1 } { 3 } π r ^ { 2 }

Explanation:

For the first question, in geometry, the standard symbol for the height of a cone (and many 3 - D shapes) is \(h\). For the second question, the base of a cone is a circle. The formula for the area of a circle is \(A=\pi r^{2}\), where \(r\) is the radius of the circle.

Answer:

1. c. \(h\)
2. b. \(\pi r^{2}\)
