The areas of two sectors of two different circles with equal corresponding arc lengths are equal. Is this statement true? Why?

the sum of the areas of two circles with radii R1 and R2 is equal to the area ofa circle of radius R, then

Two triangles have the same semi-perimeter.Do the two triangles NECESSARILY have the same area?   Yes, as their perimeters are equal.No, as their perimeters can be different.No, as their side lengths can be different.Yes, as their semi-perimeters is the same.Clear selection

Solomon needs to justify the formula for the arc length of a sector. Which expression best completes this argument?The circumference of a circle is given by the formula , where d is the diameter.Because the diameter is twice the radius, .If equally sized central angles, each with a measure of , are drawn, the number of sectors that are formed will be equal to _____.The arc length of each sector is the circumference divided by the number of sectors, or .Therefore, the arc length of a sector of a circle with a central angle of is given by or .A.B.C.D.SUBMITarrow_backPREVIOUS

(i) Area enclosed by two concentric circles with radius R and r respectively such that R > r is π(R2 – r2).(ii) The length of tangents drawn from an external point to a circle are not equal.(iii) There is one and only one tangent at any point on the circumference of a circle.(iv) Ratio of the area of the sector of a circle with central angle 90° to the area of that circle is 1 : 4.A (i)-F, (ii)-F, (iii)-F, (iv)-F B (i)-F, (ii)-T, (iii)-F, (iv)-F C (i)-T, (ii)-F, (iii)-T, (iv)-T D (i)-T, (ii)-T, (iii)-T, (iv)-T

If the sum of the areas of two circles with radii R1 and R2 is equal to the area ofa circle of radius R, then(A) R1 + R 2 = R (B) 21R + 22R = R 2(C) R1 + R 2 < R (D) 2 2 21 2R R R
