Example Question #201 : Hspt Mathematics

What is the area of a circle with a radius of 10?

Possible Answers:

\dpi{100} 100\pi

\dpi{100} 100

\dpi{100} 20\pi

\dpi{100} 10\pi

Correct answer:

\dpi{100} 100\pi

Explanation:

The formula for the area of a circle is \dpi{100} \pi r^{2}

\dpi{100} \pi r^{2}= \pi (10)^{2}=100\pi

Example Question #202 : Hspt Mathematics

What is the area of a circle with a radius of 7?

Possible Answers:

Correct answer:

Explanation:

To find the area of a circle you must plug the radius into  in the following equation 

In this case the radius is 7 so we plug it into  to get 

We then multiply it by pi to get our answer 

Example Question #203 : Hspt Mathematics

What is the area of a square with a side length of 8?

Possible Answers:

Correct answer:

Explanation:

To solve this question you must know the formula for the area of a rectangle.

The formula is 

In this case the rectangle is a square so we can plug in the side length for both base and height to yield 

Perform the multiplication to arrive at the answer of 

Example Question #204 : Hspt Mathematics

Diagram_a

Refer to the above diagram, which shows an equilateral triangle with one vertex at the center of a circle and two vertices on the circle.

What percent of the circle (nearest whole number) is covered by the triangle?

Possible Answers:

18%

It is impossible to tell without knowing the radius.

12%

10%

14%

Correct answer:

14%

Explanation:

Let  be the radius of the circle. The area of the circle is 

 is also the sidelength of the equilateral triangle. The area of the triangle is 

The percent of the circle covered by the triangle is:

Example Question #205 : Hspt Mathematics

Julie wants to seed her rectangular lawn, which measures 265 feet by 215 feet. The grass seed she wants to use gets 400 square feet of coverage to the pound; a fifty-pound bag sells for $66.00, and a ten-pound bag sells for $20.00. What is the least amount of money Julie should expect to spend on grass seed?

Possible Answers:

Correct answer:

Explanation:

The area of Julie's lawn is  square feet. The amount of grass seed she needs is  pounds. This requires three fifty-pound bags, the most economical option since it is cheaper to buy a fifty-pound bag for $66 than five ten-pound bags for $100.00. Julie will spend 

Example Question #314 : Ssat Middle Level Quantitative (Math)

Thingy

Above is a figure that comprises a red square and a white rectangle. The ratio of the length of the white rectangle to the sidelength of the square is . What percent of the entire figure is red?

Possible Answers:

Correct answer:

Explanation:

To make this easier, we will assume that the rectangle has length 5 and the square has sidelength 3. Then the area of the entire figure is 

,

and the area of the square is 

The square, therefore, takes up

of the entire figure.
