Pls help 7th-grade math

Answer 1

Step-by-step explanation:

$area \: of \: circle \: = \pi {r}^{2} \\ = \frac{22}{7} \times 10m \times 10m \\ = \frac{2200m2}{7} = 314 \times \frac{2m2}{7} \: or \: \\ 314.285714286m2$

sorry for bad editing after posting the question

PLZZZZ mark me as a brainlist

Answer 2

Answer:

25/4 π sq.meter

Step-by-step explanation:

Each section of the circle is called a sector.

They subtend equal angle,i.e, 360°/4 or 90° which is equal to π/2

Area of a sector= ½ r²∅ , where ∅ is the angle subtended by an arc at the centre.

Or, Area of the sector= ½ 5²* π/2 =25/4π m²
