7th Grade STAAR Math Review

Front

What is the formula for the volume of a rectangular pyramid?

Back

Volume = (1/3) * base area * height

Front

How do you calculate the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2πr, where r is the radius

Front

How do you set up an inequality to represent a situation where you need to earn a certain amount of money?

Back

Let h be the number of hours worked. The inequality is: hourly wage * h ≥ total cost.

Front

What is the probability of drawing a specific color bead from a basket?

Back

Probability = (number of specific color beads) / (total number of beads)

Front

What is the volume of a rectangular pyramid with a base area of 32 ft² and a height of 6 ft?

Back

Volume = (1/3) * 32 * 6 = 64 ft³

Front

If a rectangular prism has dimensions 3 in, 4 in, and 5 in, what is its surface area?

Back

Surface Area = 2(3*4 + 3*5 + 4*5) = 2(12 + 15 + 20) = 2(47) = 94 in²

Front

What is the circumference of a circle with a radius of 16 feet?

Back

Circumference = 2π(16) ≈ 100.48 ft

Front

If Sam earns $10.25 per hour, how many hours does he need to work to buy a laptop costing $550?

Back

10.25h ≥ 550; h ≥ 54 hours

Front

What is the expected number of times a green bead is drawn if there are 6 green beads in a basket of 20 beads?

Back

Expected draws = (6/20) * 150 = 45
