Answer:

158 cm²

Step-by-step explanation:

Given dimensions of the right rectangular prism:

length (l) = 8 cm
width (w) = 3 cm
height (h) = 5 cm

Surface area = 2(wl + hl + hw)

= 2(3 × 8 + 5 × 8 + 5 × 3)

= 2(24 + 40 + 15)

= 2(79)

= 158 cm²

A circular mirror has a diameter of 12 inches.what is the area, in square inches, of the mirror.

navik [9.2K]

Answer: The area of the mirror is 113.14 sq. inches [approx.].

Step-by-step explanation: Given that a circular can till 375 ft² of land in 15 min.

We are to find the area of the mirror in square inches.

The AREA of a circle with radius 'r' units is given by

$A=\pi r^2.$

The diameter of the circular mirror is 12 inches, so the radius of the mirror will be

$r=\dfrac{12}{2}=6~\textup{inches}.$

Therefore, the area of the circular mirror is

$A=\pi r^2=\frac{22}{7}\times 6^2=\dfrac{22\times 36}{7}=113.14~\textup{sq inches}~\textup{[approx.]}$

Thus, the area of the mirror is 113.14 sq. inches [approx.].

If you look at a state map with a representative fraction scale of 1:500,000; the straight-line distance between two cities is e

Leya [2.2K]

Answer:

Step-by-step explanation:

The scale factor is given as 1:500,000

i.e. original 500,000 is represented as 1 inch in the map

Hence if 12.7 inches on the map, this is a question of direct variation

So actual distance = 12.7(500000) = 6350000
