Answer 2

Step-by-step explanation:

Given: Hemispherical dome is to be painted from inside, the circumference of the Dome is 176 M.

To find: find the area to be painted.

Solution:

Tip:

$1) \text{ \bf circumference} = 2\pi \: r$

$2) \text{\bf curved \: surface \: area \: of \: hemisphere} = 2\pi \: {r}^{2}$

Step 1: Apply formula to find radius.

Given circumference = 176 m

$176 = 2 \times \frac{22}{7} \times r$

$r = \frac{7 \times 176}{2 \times 22}$

$\bf r = 28 \: m$

Step 2: Find curved surface area to be painted.

Put the value of radius in formula

$= 2 \times \frac{22}{7} \times 28 \times 28$

$= 2 \times 22 \times 4 \times 28$

$= 4928 \: {m}^{2}$

Final answer:

Area to be painted 4928 m².
