What is the area of the triangle?

Question_11

$\small 35$

$\small 70$

$\small 84$

$\small 42$

Explanation

Area of a triangle can be determined using the equation:

$\small A=\frac{1}{2}bh$

$\small A=\frac{1}{2}(14)(5)=35$

2

Michelle plays softball for her high school. She is the only pitcher on the team. She is the only player that is guaranteed to touch the ball on every play. The problem is, her hands are not big enough to get a grip on the ball because the ball is too big. What is the volume of the softball that has a diameter of 6 inches?

$36 \pi inches^3$

$288\pi inches^3$

$36\pi inches^2$

$288\pi inches^2$
