Identify the lateral area and surface area of a regular square pyramid with base edge length 11 cm and slant height 15 cm, round
Ann [662]

The surface area of the square pyramid is: 451 cm²

The lateral surface area of the square pyramid = 330 cm²

<h3>What is the Lateral Surface Area and Surface Area of a Square Pyramid?</h3>

Surface area = a² + 2al, where a is the base edge and l is the slant height.

Lateral Surface Area =  2al.

Given the following:

  • a = 11 cm
  • l = 15 cm

Surface area = a² + 2al = 11² + 2(11)(15)

Surface area = 451 cm²

Lateral Surface Area =  2al = 2(11)(15)

Lateral Surface Area = 330 cm²

In Lucy's coin collection, 15% of the coins are quarters.
stepan [7]

The total number of coins in Lucy's coin collection is equal to 80 coins.

  • Let the total number of coins be C.

<u>Given the following data:</u>

  • Percentage of quarters = 15%
  • Total number of quarters = 12 quarters

To the total number of coins in Lucy's coin collection:

Since the percentage of the quarters in Lucy's coin collection is equal to fifteen percent (15%) of the total number of coins. Thus, we would multiply the total number of coins by 15% and equate it to 12 quarters.

<u>Total number</u><u> of </u><u>coins</u><u>:</u>

\frac{15}{100} \times C = 12\\\\15C=12 \times 100\\\\15C =1200\\\\C=\frac{1200}{15}

C = 80 coins.
