Question

what is the radius and diameter of a circle that has an area of 154 cm​

Answer 1

Answer:

RADIUS IS 7 CM

DIAMETER IS 14 CM

Explanation.

let the radius of circle b r

area of circle = 154 cm

πr²= 154

22÷7×r²=154

r² = 154×7\22

r²=√49

radius = 7 CM

therefore diameter is 2r

2 × 7 = 14 cm

HOPE THIS HELPS YOU

Answer 2

$r^{2}$Answer:

Area of Circle = $\pi r^{2}$

Radius = Diameter/2

Area[given] = 154

[using the values in formula]

154 = 22/7*$r^{2}$

154*7/22 = $r^{2}$ ---[when moving from rhs to lhs... they get reciprocalled]

7*7 = $r^{2}$

49 = $r^{2}$

r = √49

r = 7cm

diameter = Radius * 2

D = 7*2

d=14cm
