The surface area of a regular pentagonal pyramid is 125 square yards. the base length is 5 yards. the area of the base is 37.5 square yards. what is the slant height of the pyramid?

Step-by-step explanation:

The total surface area is 125 square yards.

The base area is 37.5 square yards.

Hence, the area of the curved surface is 125 - 37.5 = 87.5 square yards.

According, to the formula, the area of the curved surface is , where b is the base length and s = slant height.

Here, it is given that b = 5 yards.

Thus, .

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
